How to measure the cube of an edged board. Calculation of the volume of lumber

Any construction work begins with a project and an estimate, which implies the calculation of the amount of materials. Edged board is one of the most popular materials from the assortment of timber merchants. The basic unit of measurement for any lumber is 1 m 3. However, it is important for the end user to know the number of boards in a cube of a certain length and thickness.

Instruction

Sometimes the manufacturer leaves a label on the materials indicating the price of the package and the exact volume. But often the storekeeper makes the measurement.

The calculation of cubic capacity will depend on the degree of processing of the material, type and variety. For example, edged and unedged boards are calculated differently. Also, for breeds, calculation methods can be different. For coniferous and deciduous, you can use both the measurement and multiplication of the sides, and the standard designed to calculate the volume. The second method is the use of a collection of tables, where each meter of length and one piece of material corresponds to a volume. They are called cubers.

To find the number of cut boards in 1 cube, you need to find out the volume of one of them by finding the product of three quantities, and then divide 1 m 3 by it.

Example:

• Section 150x25 mm
• Length 6 m

The first step is to translate all values ​​​​in meters: 150x25 mm \u003d 0.15x0.025 m

0.15 x 0.025 x 6 \u003d 0.0225 m 3

We determine how many boards are in one cube: we divide 1 m 3 by the cubic capacity (the volume of one board):

1 m 3 / 0.0225 = 44.4 pieces

Calculation may be required, for example, when determining the cost. So, if we take the price per cube equal to 6,500 rubles, then with a cubic capacity of 0.0225 m2, one will cost 146.25 rubles. But often the volume is rounded up to 0.023. And then the materials cost the buyer 149.5 rubles apiece. And when rounding the amount, the overpayment for 1 m 3 is 1%.

The calculation for unedged boards is made differently. If only one piece is purchased, then its length and thickness are measured in the same way as for edged material. But the width is taken as an average. For example, if it can vary from 15 to 23 cm at different ends, then you need to take the value in the middle.

If you want to find the volume of a large number of boards, then they need to be sorted in piles according to the maximum match in length and width. It is better if the error does not exceed 10 cm. The height of the stack is measured with a tape measure in the middle of the board and the length. The result is multiplied by a special coefficient, which depends on the air gap and is 0.07-0.09 units and is taken from the cubature reference book.

The table shows the estimated number of edged boards of spruce, pine, cedar and larch in a cube of lumber. The standard length is taken as 6 m, and the width is from 100 to 250 in 50 mm increments. The thickness is 25-50 mm.

Before starting construction work, any owner of land real estate on which it is planned to build a residential building wants to know how much material will be needed. Financial costs will depend on the volume of building materials and their type, which can be difficult for some owners to bear at a time, and they are forced to purchase various materials in stages. In low-rise housing construction, wood and products made from it make up a large part. Therefore, it is desirable to know how many boards will be needed and how much they will cost.

Thanks to the accurate calculation of the number of boards, you can save a lot and not be deceived.

Characteristics of wood materials

Currently, the building materials market offers various wood materials at a price in rubles per cubic meter. If how many boards are needed for arranging the floor, I would like to know their price. In addition, construction requires different types of wood products that differ in shape, size and price. Therefore, before studying the question of how many boards are in a cube, it is necessary to study the range of proposed wooden products. A future homeowner, in order to build his future home, may need:

• profiled beam of square or rectangular section, the smaller side of which exceeds 100.0 millimeters;
• bar whose size is:
• ü 16.0 ... 75.0 millimeters for products sawn from softwood;
• ü 19.0 ... 100.0 millimeters for hardwood.
• edged, processed in three planes, a board with a thickness of more than 20.0 millimeters, the width of which varies widely;
• unedged board, having two sawn sides, the side edges of which are unfinished;
• slab, which is half sawn timber from round timber ;
• terrace board http://www.ecowood.com.ua/catalog/terrasnaya-doska for flooring.

The greatest financial costs will be required for the purchase of the first three types of lumber, so the solution to the question of how much timber, bar or boards in a cube is most relevant.

Accurate calculation of the amount of lumber in one cubic meter (1 m³)

The task of determining how many boards in a cube is at the level of arithmetic tasks solved in the first grade. The initial data for calculating how many beams, bars or boards in a cube are:

• z is the number of boards (pieces);
• h is the thickness of the board (the smaller section of the bar) in meters;
• b - lumber width (meters)
• L is the length of a lumber unit (meters).

The volume (V) of one product (board, beam or bar) is determined by the ratio:

V = h × b × L, cubic meters,

and the number of lumber units in a cubic meter is defined as:

Of course, this calculation is quite approximate - it does not take into account the gap between individual products, the type of board processing (groove, planed), length allowance and other rather specific little things. According to the above formulas, it is impossible to calculate the number of unedged boards or slabs. However, to determine how much to take with you to the lumberyard, and whether an extra thousand rubles will interfere there, accuracy is enough. More accurate results can be obtained using the tabular calculation method.

Tabular determination of the amount of lumber

To determine how many boards are in 1 cube, the calculation table contains columns and lines. The lines indicate the cross section of the lumber, and the columns (rows) show the calculated values ​​​​of the volume of one board and the number of boards in one cubic meter. In principle, these values ​​are obtained by calculation, but taking into account correction factors. Consider a clipping (part) of the table how many boards are in 1 cube. In this case, the symbols correspond to those used in the above formulas.

Calculation table for non-standard boards and timber

The construction of a private house, cottage or any other building requires an estimate. It indicates the number of building materials and their cost. There are several methods for performing the corresponding calculations. The board is a common material that is used everywhere. In order to determine how many boards are in a cube, you need to familiarize yourself with the calculation options and the nuances of this process.

How many boards in a cube: varieties of lumber and features of their calculation

The boards that are used in the construction of houses and other structures differ in several ways. First of all, the material from which they are made is taken into account. The technical characteristics of the product depend on the type of wood. Depending on the method of production, these building elements are divided into types:

• edged;

• unedged.

The first of them belong to the highest grade and have the correct shape, since all their faces can be processed. In turn, unedged products are most often used for organizing rough flooring, etc. The peculiarity of this material is that its side edges are not processed, they contain bark and have a natural shape. This simplifies the production of unedged boards and affects their cost.

In order to answer the question of how to calculate the cube of the board, you must first decide which of the materials will be used in the construction process. For example, it is easier to calculate the cubature and cost of an edged part, since it has a geometrically correct shape.

For unedged products, there are constant values ​​that are arithmetic averages. A table of boards in a cube in this case is not always suitable, since it takes into account the rounding even of edged lumber.

Separately, it should be said about building materials for fine finishing. This group includes lining, block house and products that imitate timber. The design of these finishing parts includes special ribs and grooves necessary for tight connection of individual elements to each other.

Helpful information! When calculating the finishing lumber, you need to focus only on the dimensions of the main part of the board. Thus, the size of the locking joints is not taken into account, only the numerical values ​​​​of the product body are taken for calculation.

Regardless of what type of material is used, a single formula is used to calculate the number of boards in a cube. An exception in this case are unedged products. Their calculation has its own characteristics, because such parts do not have all the faces necessary for the calculation.

Cube volume formula: how many edged boards are in 1 cubic meter

A cube is a geometric figure that consists of 6 equivalent faces. Each of them is a square. To determine the volume of this figure, it is necessary to multiply 3 indicators among themselves:

• length;

• width;
• height.

In order to find out how many boards are in 1 cube, you need to multiply several values. The result is a mathematical expression that looks like this:

V = h x b x L, where:

h is the height of the edged product (m);

b – element width (m);

L is the length of one part (m).

Using this formula, you can determine the volume of 1 element. It is important to remember that when carrying out the calculation, it is necessary to convert the millimeter values ​​\u200b\u200bof the product into meters. For example, in order to determine how many boards 25x150x6000 in a cube, you need to convert the numbers by multiplying them by 0.001. The finished mathematical expression after such a transformation will look like this:

V = 0.025 x 0.15 x 6

The result is that the volume of one piece of wood is 0.0225 cubic meters (m³). Next, it remains to calculate how many pieces of edged boards are contained in 1 cubic meter. There is a simple formula for this. It involves dividing 1 cubic meter by the volume of 1 board, which was obtained using the past mathematical expression. Consider the calculation on an example:

1 m³ / 0.0225 m³ = 44.4

Thus, 1 cubic meter contains approximately (if rounded up) 44 boards. After that, it is already possible to independently determine the amount of material needed for the construction of a particular structure. And also at this stage, you can draw up a general estimate indicating the price of edged boards per cubic meter.

To calculate the cost of 1 edged board, a mathematical expression is used, which involves multiplying the volume of 1 part by the price of a cubic meter. Let's look at an example:

0.0225 x 8200 rubles = 184.5 rubles.

The calculation showed that the cost of 1 product of the cut variety will be approximately 184 rubles. If the cost of 1 part is known, but it is necessary to calculate the price of a board cube, you need to do the reverse manipulation. In this situation, you will need to divide the price for 1 item (184.5) by its volume (0.0225).

Note! Sometimes, especially when buying a small batch of boards, there is confusion with decimal places. In some cases, lumber vendors will specifically quote a value calculated by rounding up to the 3rd number. However, by law, this value is only suitable for large batches of boards. When purchasing several products, it is recommended to round off according to GOST, namely up to 0.000001 m³.

When calculating the number of boards and the cost of lumber per cubic meter, it is desirable to take into account unplanned losses that very often occur during construction. Therefore, it is recommended to buy edged products with a small margin (several pieces).

How many boards in a cube: calculation of unedged lumber

The calculation of the cubature of an unedged board has some nuances, since its shape is not correct. Such material does not have a rectangular section along its entire length, so it is used to organize temporary structures. The lower and upper surfaces of unedged boards must be processed along the entire length. Otherwise, this product is the side part of the log (slab).

To find the volume of unedged lumber in 1 cubic meter, as well as its quantity, there are several methods. It should be noted right away that it is quite difficult to determine how many boards are in one cube when it comes to irregular geometric shapes. Therefore, the initial numbers obtained when calculating unedged parts will be an approximate indicator.

Consider what methods are used to calculate the cubic capacity and the amount of unedged lumber:

• batch;
• piece;
• sampling method.

In the first case, you will need to load the lumber into a package, which must have the correct shape. After bookmarking, it is necessary to measure the necessary indicators. Next, a standard procedure for determining the volume is carried out using the values ​​​​obtained during the removal of measurements. This method is most common for products that do not have clear edges. For example, with it, you can calculate the cubes of a 25x150x6000 board in a cube (unedged).

It is worth noting that in this type of mathematical expression, a special coefficient (for width) is used, which is the arithmetic average. Although this option is not fast, it allows you to answer the question of how to calculate the cube of the board.

The piece method involves the use of numbers corresponding to the arithmetic mean values ​​​​of the height and width of the edged product. These values ​​are calculated in meters.

In order to find the arithmetic mean, you need to measure the board. The minimum width (at the narrowest point) and the maximum are measured. The two scores are then added up and divided in half. After that, the same height manipulation is performed. The numbers obtained during the calculation must be multiplied by each other and by the length of the product.

Let's see how it looks like in the form of a mathematical expression:

(b max + b min) / 2 x (h max + h min) / 2 x L = V

Using such a formula, it will not be difficult to determine the volume of 1 unedged element and answer the question of how to calculate the cubature of the part. After obtaining this value, you can calculate the total number of boards in a cubic meter. For such a calculation, you will need to use a formula similar to that for a trimmed part (a cubic meter is divided by the volume of the product).

Helpful information ! When buying raw boards, you need to be careful. Sellers should use a factor that affects the reduction in total volume, taking into account future shrinkage. To calculate wet coniferous products, 1 cubic meter must be multiplied by the number 0.96. In turn, the coefficient for hardwood is 0.95.

The last way to determine the volume of lumber and its quantity in 1 cubic meter is the sampling method. It is used in the calculation of large batches of wooden building materials. The essence of this method is that several boards are selected from the total mass. Then the parts are measured and calculated according to the piece by piece method. The resulting numbers are multiplied by the total number of parts in the lot.

How many boards in a cube 50x150x6000 in a cube: calculation

As an example, you can take an unedged product with dimensions of 50 by 150 by 6000 mm. First, we convert millimeters to meters. Some people don't know how many millimeters are in 1 meter. To convert, you need to multiply the required number in mm by a factor of 0.001. In finished form (with substituted values), the formula will look like this:

(0.155 + 0.145) / 2 x (0.055 + 0.045) / 2 x 6 = V

After adding and dividing by 2, we get the arithmetic average of the width and height of the unedged part. Thus, the formula takes on a more understandable, standard form:

0.15 x 0.05 x 6 = 0.045

This is how a calculation is made, the result of which is finding the volume of 1 board. To determine the number of products in 1 cubic meter, the same formula is used as in the case of a trimmed counterpart.

If necessary, you can calculate the area of ​​​​one board. Most often, this is required when the manufacturer indicates the price per square meter, and not per cubic meter. The area formula involves multiplying the width of a part by its length. It is important in this case not to make a mistake and not to forget to convert millimeters to meters.

In order to determine the cost, the same formula is used as in the case of edged lumber. You just need to multiply the volume of 1 part by an amount that corresponds to the total price of the cube. This is how the calculation of cubes in the cube of the board 50x150x6000 is performed.

Calculating the board with an online calculator

Perhaps the easiest way (along with the lumber cube table) to determine the exact value of the volume and number of wooden boards is an online calculator. It is a program with preset algorithms that allow you to calculate all the necessary lumber values. This method makes it possible to calculate not only the edged board, but also other varieties of these products.

Note! In order to avoid the possibility of an error when calculating the material on the online calculator, you should immediately indicate for which board the measurement is used.

The process itself is quite simple. First you need to find a calculator on one of the specialized sites using the search line of the browser. Next, you will need to enter the required indicators in the appropriate cells. The board calculator in the cube will calculate on its own.

This method is popular and allows you to quickly and accurately determine all the necessary lumber values. When using a calculator, it is recommended to check the accuracy of filling several times. In the event of an error, the calculation will be performed incorrectly, which is fraught with serious discrepancies in the final figures.

How many boards in a cube: table (6 meters)and tips for its use

The last method to determine the quantity and cubic capacity of wooden products is to use a special table. This method is very convenient, as it does not require long calculations. All that is needed is simply to find the desired value in the table using the initial data (width, height and length).

In order to quickly find the correct answer to the question of how many boards are in one cube, the table is the best fit. However, experts point out one drawback of this method: the numbers corresponding to the cubic capacity or quantity are often rounded off. Therefore, if you need to perform the most accurate calculation, it is recommended that you do all the calculations yourself.

Edged board volume in a cube:

In addition, before starting the search for the desired value, it is advisable to make sure that the length of the lumber matches. The tables can be different, containing information about the cubature of boards with a length of 3, 4 or 6 m. Today, the most common are wooden products, the length of which is 6 meters. How many boards are in one cube? The table that allows you to determine the amount of lumber also uses rounded values.

Do not forget that the board can be made from different types of wood. Therefore, before using the table, it is recommended to make sure that you have selected the required type of lumber.

How many boards in 1 cube: table (6 meters):

The tabular method is good because it does not require calculations or self-filling of overall and other lumber values ​​​​to get an answer. It is suitable for determining the cubature, and also allows you to answer the question of how many boards are in a cube. The table is ideal for calculating large batches of a product.

Edged board prices per cube: 50x150x6000and other varieties

Today in the construction market you can find many varieties of lumber. All of them are differentiated not only by size, but also by the type of wood from which they were made. And also the cost of these products is influenced by the production technology and their purpose. In order to find out how much a board cube costs, you need to familiarize yourself with all the varieties of these details.

The most popular in the construction of private houses, cottages, as well as other structures is a classic edged board. It can be 1st and 2nd grade. The first option is more expensive, as it has higher technical characteristics and durability.

Helpful information! The price of a 1st grade edged board is approximately 7,500 rubles. for 1 cu. Products that belong to a lower quality group cost about 4-6 thousand rubles. for 1 m³.

The width and height of the boards, as a rule, does not affect their cost. This is due to the fact that in a cubic meter, regardless of the dimensions of wooden lumber, there will be the same number of parts. In the sense that for the same price you will receive 44 edged boards 25x1500x6000 (price per cube: 7500 rubles) or 22 parts 50x150 having the same length.

Separately, it is worth mentioning edged boards made in accordance with the technical specifications (TU). Lumber of this type costs an average of about 7,000 rubles. per cube Such boards are distinguished by good quality characteristics and can be used in the construction of various structures.

Unedged products are cheaper, as they are of lower quality. Their cost is calculated using averaged values. The price of unedged lumber ranges from 4 to 5 thousand rubles. However, they are not recommended for construction. It is better to use better quality lumber, for example, edged board 40x150x6000 (price per cube: 7500) or similar products with other dimensions.

When buying wood lumber, you need to pay attention to some points. For example, the board must be flat. The curvature of the product most often indicates that the technology was violated during its production. Such parts are not used in construction, as they do not have the required quality.

How much does a board cube weigh? When purchasing this building material, its mass should be taken into account. So, for example, a cut board made from dry spruce weighs 450 kg (1 cubic meter). 1 m³ of raw products has a mass of 790 kg. Dry pine has a weight of 470, and raw - 890 kg. This knowledge will be needed when transporting products.

When choosing lumber and its calculation, you must be careful. The board must not have cracks, chips or other defects. Small cracks are allowed, but it is recommended to buy a solid, high-quality product that meets GOST. You should also pay attention to the presence of knots. This is due to the fact that they negatively affect the strength of the wooden part. The choice of calculation method depends on the specific case. If necessary, you can always use the services of specialists who will help you perform the correct calculation and draw up an estimate.

It would seem, why do you need to know how many boards are in one cubic meter? After all, with a large construction, boards are sold anyway in “m 3” and payment is made precisely for the volume, and if only a few pieces are needed, then the cost is determined by linear meters. And yet, it is necessary to understand how such a calculation of the material is made.

With the proper organization of work, the first stage is always such an item as planning. And not only the design and features of the future structure, but also material costs. Therefore, if in accordance with the project 40 boards are required, then, given the marriage or inaccuracy, you will have to buy - with a margin - 45 pieces. For this, you should calculate how many “cubes” you need to purchase and add a few more blanks to them.

Why?

First of all, the number of boards in 1 m 3 depends on their parameters (thickness, length, width). Naturally, for each size their number in the "cube" will be different.

Secondly, when carrying out any work, whether it is a new building or renovation, different boards are always used. For the rafter system - one, for the floors - others.

Thirdly, buying extra material is a waste of money. Of course, the boards will come in handy later, but they need to be stored somewhere. And not just leave it on the site, and then get "rotten", but provide the proper conditions. And given that we have never had a shortage of wood, is it worth buying much more than necessary?

Fourth, time factor. And if there are not enough boards when purchasing in cubic meters? What, stop work, look for trucks, waste time going to points of sale?

And fifth, you should not hope that the Seller will answer such a question. At best, he will offer to count the boards in piles himself, if interested. At worst, on purpose or out of ignorance, he will deceive.

We offer you a table with ready-made data:

It has only 3 columns. The first shows the dimensions of the blanks (in "mm"), the second - their number in 1 m3, and the third - the volume of 1 board (also in "m3"). There is nothing complicated. It is only necessary to find the corresponding line, and the answer to the question of interest has been received.

By the way, it's very convenient. If we multiply the entire required number of boards by the volume of one, it will become clear how many "cubes" will have to be purchased, which means how much money will have to be spent. This is exactly what a good owner should do. And tables are not needed, just use a calculator.

This table provides data for both edged and unedged boards. In addition, there are calculations for, which is also often used in construction or repair.

In principle, this is quite enough.

Note

All of the above is true if the edged board is purchased. But it also costs more. It is more cost-effective to take raw material if it is possible to trim it yourself. But in this case, it is necessary to apply a coefficient when calculating. Experts believe that 20-30 percent of unedged lumber will go to waste. Therefore, from 1 "cube" of finished boards, you will get less.

Any construction or repair work with wood requires a painstaking calculation of the required amount of this building material. How to correctly calculate how much to buy this material so that you don’t spend extra money and have enough for everything planned in full? Below is the formula and rules for calculating cubic meters of wood, which will help eliminate even the slightest errors!

What are lumber

What is lumber - perhaps everyone understands. This is a tree already sawn on special equipment.

The process of preparing lumber is always the same:

1. Wood (round timber, i.e. logs) is brought to the sawmill;
2. Next, this primary timber is sorted according to the directions of subsequent processing, in order to eventually obtain a building material from a tree of the required size (length) and cross-sectional area (width + thickness).

You should be aware that timber and any kind of lumber will be measured in cubic meters. According to the construction and mathematical standards, a cubic meter is a three-dimensional square, for the length, width and height of which one meter is taken.

In order to accurately determine whether there are enough wood building materials for a specific construction task, it is necessary to take into account the dimensions of the resulting edged board and the features of its primary woodworking.

Edged timber

This is the most sought-after lumber for construction or renovation, which can be of various lengths and cross-sectional sizes. If you know these sawing parameters, it is easy to find the values ​​\u200b\u200bof how many boards are in a cube.

For example, we received boards 50 x 150 x 6000 mm in the amount of 25 pcs. To calculate how many cubes it is, you can use a special table. There are only three columns, according to the testimony of which it is easy to calculate how many boards are in one cube. Since we have 25 boards, it is easy to find out what cubic footage it is: divide 25 by the value obtained (how many boards are in 1 cube in a table of 6 meters).

Planed timber

Unlike edged timber, which has natural moisture, planed timber is qualitatively dried. As a result of timber drying, its volumes and weight slightly change (decrease):

1. If undried wooden lumber is used in construction, then when it dries, the surface may change its shape (twisted or bent timber).
2. The quality and durability of the structure as a whole will depend on how much the building material weighs.

Another difference between planed timber and other types of lumber is a strict regularity in the initial dimensions: the length of the timber section should not exceed 2 times in relation to the width dimension.

planed bar

According to construction GOSTs, there is a certain index by which a bar is distinguished from a bar. This is the section width: if this parameter is greater than 100 mm, then we have a bar in front of us, and if the section width is less than (or equal to) 100 mm, we are dealing with a bar.

Edged bar

Edged bar (by analogy with edged timber) is freshly sawn (or without high-quality drying) lumber.

The difference between edged or planed timber / timber is practically conditional, because you can change the width of the material by 2 - 3 cm (and therefore change the status of this material) at the sawmill without any problems.

Professional builders choose timber for the intended use, considering only 3 features:

1. The type of wood from which the beam is made;
2. Drying time of this log house;
3. Features of the building structure (weight load), for the construction of which building materials are selected.

Edged board

This is a kind of lumber with certain dimensions: the width must be 2 times greater than the thickness of the section. The bearing capacity of such a building material is less than that of a bar.

Because their purpose is appropriate:

1. Interior works (floor, roof, walls);
2. External arrangement (fences, siding, construction of outbuildings, etc.).

floor board

According to the dimensions and purpose, there are various types of floorboards (or lining).

To date, the building materials market offers such types of wall paneling, which does an excellent job with sheathing any surface:

1. Parquet - the highest quality and practical properties of this type of flooring are provided by the internal structure in 3 layers: spruce, wood-fiber from conifers and decorative from fruit trees, ash, oak.
2. Terraced - consists of natural wood + some polymers. Differs in high tolerance to humidity, temperature fluctuations, light.
3. Sexual ordinary is a pure wood material. Pine lining is used for arranging floors, walls, ceiling coverings in residential premises. Lining made of aspen or linden is ideal for a bath, larch lining is used for arranging street buildings (arbors, terraces, etc.).

By quality, lumber for the floor is divided into classes:

1. The highest (or selective) is used only for elite buildings with extremely high wear resistance and reliability;
2. The first and second are applicable for the construction of ordinary housing;
3. The fourth is exclusively suitable for outbuildings.

How to measure

Calculating a sufficient amount of lumber is a responsible task. To calculate how many pieces you need to buy to complete repairs for a specific floor or wall area, you should know the cubic footage of these lumber.

The task is not difficult, but pedantic, and begins with calculations for one board:

1. The width, length and thickness of a lumber unit are indicated in millimeters, which should be converted to meters;
2. Multiply the obtained values ​​\u200b\u200b(width x length x thickness) - this is the cubic footage of the board / beam.

Now, in order to estimate how many such boards / beams are in a cube, you need to divide 1 m 3 into the resulting product of the external dimensions of the building material and round up to a whole value. This will be the desired result.

How many boards in a cube: timber table

In order not to waste time on measurements / calculations, you can use a ready-made table. Here, according to the known dimensions of the timber, it is easy to calculate how much timber is in 1 cube and what is the volume of one timber.

How many boards in 1 cube: board table

There is a similar table for boards: knowing in advance (or measuring it yourself) the initial dimensions, it is very easy to find out the volume of a unit of a given building material and how many boards of this size are in a cube.

The formula for calculating the board in a cube in squares

To calculate the surface area, only two indicators are used: length and width. Therefore, in order to calculate the required amount of lumber for work, the cubic capacity of lumber should be converted to square, and compared with the surface area.

Make it easy: 1 m 3 divided by the thickness of the selected unit of building material.

The formula for calculating the board in a cube in pieces

To determine how many boards of a given size in 1 cubic meter, you should:

1 m 3 / board volume (i.e. length x width x thickness)

The formula for calculating the volume of the board

Volume is a three-dimensional quantity. To calculate the volume of the board, you should take the product of width, thickness and length. But, the situation is simplified if you take a meter beam or board. In this case, we multiply only the remaining two values: the thickness and the width of the section.
