What is a cubic meter of edged board
How many edged boards in one cube - Photo
Edged board- lumber with cleanly cut edges, without bark residues. The width of the edged board exceeds the thickness at least twice.
Since the fee is charged for the volume in cubic meters, we recall the geometric formula for its definition:
W * H * D = volume.
Everything is in meters.
To find out how many boards are in one cube:
1 / (W * H * D) = number of boards in 1m3 (cube)
where, W- Width, AT- Height, D- Length
Translation: 1mm=0.001m, 10mm=0.01m, 100mm=0.1m

When buying lumber in small quantities, you can get confused with decimal places, namely with rounding. An experienced seller will round the resulting number to the 3rd decimal place. The experienced buyer will round up GOST y - up to 0.000001 cubic meters and remind the seller that up to 0.001 cubic meters. meters are rounded only a batch of boards. The most common quantity - from several boards to 2-4 cubic meters - does not make up a batch. In order not to offend either one or the other, they are rounded to 4 decimal places.
Then the resulting volume is multiplied by the cost of 1 m3 (cube). And here the number of decimal places can significantly affect costs.
1 edged board 32 mm thick, 200 mm wide and 6 m long(32X200X6000) has volume
- 0.032 * 0.2 * 6 = 0.0384 cubes
30 boards will have volume
- 0.0384 * 30 = 1.152 cubes
If the seller rounds the volume of 1 board to 0.04 cubic meters, he will additionally receive income:
- 0.04 * 30 \u003d 1.2 cubes
- 1.2 - 1.152 = 0.048 cubes
Selling these 0.048 "air" cubes makes the buyer's wallet easier
The cost may vary depending on the type of wood. Grading decreases with a decrease in quality: the presence of wood defects and deviations from standard sizes. If the floorboard has a curvature, narrower or thinner than the standard by 3-5 mm, it will not work completely. Visual inspection of the lumber is just as important as accurate sizing.
Edged board area covered
To find out how much lumber you need, the calculation of the board in a cube will help you. The above formula is based on the definition of area
W * D = area.
Having calculated the covered area, it remains to multiply it by the desired thickness of the board
W * D * 0.022; 0.025; 0.032; 0.04m and so on.
It remains to see how many boards are in one cube, and determine the required number. Just in case, print or memorize the table above.
You also need to take into account the future cutting of the material.The floor and sheathing boards "lining" have an overlapping tongue, which is taken into account in the cubature, but is not included in the area to be covered. A couple of boards are needed have in reserve .
Determining the volume of unedged boards
How many unedged boards are in one cubic meter - Photo
Unedged board, that is, not having a rectangular section along the entire length, is much cheaper and is widely used for the installation of various kinds of rough battens, temporary fences.
It is important to understand that the top and bottom of such a board must be sawn along the entire length. If one face is not propylene, then this is already croaker. The definition of the cubic capacity of such lumber differs precisely in that it does not have the correct geometric shape.
The current standards establish several ways to account for unedged material, and it is almost impossible to calculate exactly how many boards are in 1 cube.
- Batch.
- Piece by piece.
- Sampling method.
In batch In this case, the boards are tightly packed into a bag of the correct shape with further measurement. Further calculation is carried out according to the standard formula for determining the volume. using various coefficients.
Piece measurement made according to average measurements of height and width. The largest and smallest dimensions in meters are added and divided in half.
(Wmax + Wmin) / 2 * (Hmax + Hmin) / 2 * L = volume, m3
where, W- Width, AT- Height, D- Length
If it is visually visible that the wood is fresh and, accordingly, damp (humidity above 20%), then the seller is obliged to reduce the total volume by multiplying the received cubic capacity by the coefficient:
- 0,96 for softwood
- 0,95 for deciduous.
Sampling method used to determine the volume of a large batch of unedged lumber. When loading, for example, into the body of a vehicle, every fifth, tenth or twentieth board is measured using the second method.
The resulting volume is multiplied by five, ten, twenty. Loading continues to the next control board. The selection of control boards in a separate foot is also practiced. The calculation is made after the loading is completed.
Calculating the volume of a bar: how much is a bar in a cube?

The beam differs from the edged board only in that all its faces or two opposite ones have the same size: more than 0.05 m in thickness and 0.013 m in width. The formula for determining its volume is standard

W * T * D = volume of timber, m3.
To find out how much timber is in one cube
1 / (W * T * D) = amount of timber in 1 m3 (cube)
where, W- Width, T- thickness, D- Length
Translation: 1mm=0.001m, 10mm=0.01m, 100mm=0.1m
When buying a beam, the volume must be determined by the piece, since the beam is laid with spacers in the stack. The measurements of such a stack and the calculation of the cubature according to the above formula invariably lead to a significant overestimation of the volume.
Length of 1 cube of timber (and any edged lumber) in meters is determined by dividing the unit by thickness and width. For example, you need to find out how much timber is in one cube - a face of 180 mm.
1 / (0.18 * 0.18) = 30 meters 87 cm.
1 meter of such a bar will have the following volume.
0.18 * 0.18 * 1 = 0.0324 m3.
These calculations may be needed when determining the cost of funds and material.
Construction log volume: how many logs are in one cube?
How many logs in one cube: calculation - Photo
Log buildings are and will be relevant. The determination of the volume of round material depends on the method of its production.
- Construction log of manual debarking.
- Construction log, rounded on special machines.
The section of the barrel for trimming by hand has the shape of a slightly truncated cone, so the cylinder volume formula is used, but with some peculiarities.
3.14 * r2 * L = log volume, m3
Here
r- average radius, calculated as (r1+r2)/2, r1 is the radius from one end of the log, r2 is the radius from the other end of the log.
L- log length.
3,14
- constant "Pi".
The rounded log has, of course, a cylindrical shape and is calculated according to the above formula. But here the radius is measured at any end once. Determining the number of logs in 1 cube is determined similarly to a bar.
1 / (3.14*r2 * L) = Number of logs in 1m3 (cube)
Blanks for construction logs are measured in the same way.
The radius (diameter divided in half) is measured without taking into account the thickness of the tree bark. In practice, manual calculations are not carried out. They use special tables summarized in a cubature book. They are also available in electronic form.
In conclusion, it should be noted that lumber for critical work, standard in size, wood species and humidity, should be purchased at large sites. A small manufacturer, as a rule, is not allowed there due to the lack of appropriate control over the quality of their products.
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 grade. 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 need 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.

In order not to waste time in the process waiting for the delivery of lumber and the problem of shortages, you should immediately calculate the required quantity and place an order with some margin. Initially, it is worth knowing how many boards are in a cube. The table given in the regulatory documents will help you quickly determine the desired value. You can also use the cubic meters calculator developed by our team, with which it is easy to determine the number of a specific size online. We suggest that you familiarize yourself with the possible methods to make it easier to choose the best one.
Everything starts with choosing the right material. Manufacturers offer lumber of different sizes, shapes and degrees of processing. Each of these indicators can have a significant impact on the cost. In order not to overpay, we suggest that you familiarize yourself with the most popular types of lumber, as well as their possible area of \u200b\u200buse.
Edged timber
The most popular type, widely used at the stage and repair work. Can have different sizes in all directions. Made from solid wood. All facets of the material are processed.
To find out how much will be in the cube, you need to know the sawing parameters. By multiplying the length by the cross-sectional area, you can find the volume of one product. To determine the amount of timber in a cube, it will be necessary to find the reciprocal of the volume found, expressed in meters. If it is initially known how much is required, the volume of one product will need to be multiplied by the required quantity. In more detail, how to calculate the cubic capacity, we will tell further.
Attention! Edged material has a natural moisture content. In reference tables, you can find the numerical value of moisture for different woods.
Planed timber
Lumber of this type in the manufacturing process must be dried. This affects the dimensions and weight of the finished lumber, as well as its service life. When determining how much a board cube weighs, this factor must be taken into account.
Planed timber has a high-quality surface that can be used in industry. Its sides in cross section are 1 to 2.
planed block
According to its characteristics, the bar is similar to the bar. The difference, according to regulatory documents, lies in the geometric parameters. If the width of the product is a maximum of 100 mm - this is a bar. Otherwise, we are talking about a beam.
Edged bar
Lumber with natural moisture content. It is similar in characteristics to a bar, but has smaller dimensions. When choosing, you should pay attention to:
- What kind of wood was it made from?
- how long did it take to dry?
- for what design is purchased.
Edged board
It is made from wood of natural moisture. It has a width twice the thickness in cross section. This significantly reduces the bearing capacity compared to timber. Most often used when performing construction work inside a building: when installing, flooring, walls. Suitable for the construction of a fence, outbuildings. The most popular board is an inch, the dimensions of which can withstand a significant operational load.
Floor board
Timber with a purpose. Manufacturers offer several types of floorboards:
- Parquet, characterized by high quality, we provide a three-layer structure;
- , combining the characteristics of natural wood and high-quality polymer;
- Usual made entirely of natural wood. Appropriate option for the device.
Attention! Choose a material that is thick enough for the specific service load.
Knowing how many square meters are laid, and how many boards are in a cube, you can calculate the thickness of the laid material.
Unedged materials
During the production process, such material is not processed from all sides. As a result, the finished product has two wide longitudinally placed plates and unsawn sidewalls. It is in demand in the construction of premises for various purposes, formwork, decking, as well as in the performance of various non-responsible construction works.
Before you count the cube, do not rush to look for the appropriate formulas. If you do not want to perform time-consuming calculations, reference tables will come to the rescue. How many boards in a cubic meter can be found with their help in a matter of minutes.
How many boards in a cubic meter according to the table
To begin with, it is worth noting that the dimensions of lumber are standardized. Using the regulatory documents, it is easy to find out how many boards are in a cube. To do this, you need to decide what size material will be used in the construction work.
If you could not figure out how to use the tables, you can use the online board calculator in the cube, or do the calculation yourself.
The basic procedure for calculating the number of boards in a cubic meter
Before proceeding with the calculation, it is worth knowing how to calculate a cubic meter. Such a volume will be numerically equal to a cube, each side of which is equal to a meter. To find the desired value, it is necessary to multiply the linear dimensions of the figure among themselves.
To begin with, the volume of one product is determined. If we are talking about a cut board, we multiply the linear dimensions of the board: length by thickness and width. If they are given in millimeters (mm), be sure to convert to meters. Otherwise, in the future it will be possible to get confused in the dimension.
After the cubature of one board is found, the calculation procedure depends on what initial data is. If you need to calculate the number of products in a cube, we find the reciprocal of the value found. In other words, when calculating the unit (1 cube), we divide by the calculated value. The resulting value should be rounded up to a larger integer.
If the material is purchased for a specific surface, you will need to know the dimensions of the room in order to calculate the quadrature of the room. To determine the required amount of lumber, cubic meters are converted into squares. To find out how many square meters are in a cubic meter, you need to divide the cube by the thickness (height) of the selected material.
If you are afraid of making a mistake when calculating the required amount, you should calculate the board in a cube on a calculator. A special program using standard formulas will allow you to determine the desired value much faster compared to independent calculations.
Board cubic capacity calculator
For those who are afraid to make a mistake when performing the calculation, we suggest using the board cubature calculator. With it, you can find out how many boards you need in a split second.

The cost may vary depending on the type of wood. Grading decreases with a decrease in quality: the presence of wood defects and deviations from standard sizes. If the floorboard has a curvature, narrower or thinner than the standard by 3-5 mm, it will not work completely. Visual inspection of the lumber is just as important as accurate sizing.
Edged board area covered
To find out how much lumber you need, the calculation of the board in a cube will help you. The above formula is based on the definition of area
W * D = area.
Having calculated the covered area, it remains to multiply it by the desired thickness of the board
W * D * 0.022; 0.025; 0.032; 0.04m and so on.
It remains to see how many boards are in one cube, and determine the required number. Just in case, print or memorize the table above.
You also need to take into account the future cutting of the material.The floor and sheathing boards "lining" have an overlapping tongue, which is taken into account in the cubature, but is not included in the area to be covered. A couple of boards are needed have in reserve .
Determining the volume of unedged boards
How many unedged boards are in one cubic meter - Photo
Unedged board, that is, not having a rectangular section along the entire length, is much cheaper and is widely used for the installation of various kinds of rough battens, temporary fences.
It is important to understand that the top and bottom of such a board must be sawn along the entire length. If one face is not propylene, then this is already croaker. The definition of the cubic capacity of such lumber differs precisely in that it does not have the correct geometric shape.
The current standards establish several ways to account for unedged material, and it is almost impossible to calculate exactly how many boards are in 1 cube.
- Batch.
- Piece by piece.
- Sampling method.
In batch In this case, the boards are tightly packed into a bag of the correct shape with further measurement. Further calculation is carried out according to the standard formula for determining the volume. using various coefficients.
Piece measurement made according to average measurements of height and width. The largest and smallest dimensions in meters are added and divided in half.
(Wmax + Wmin) / 2 * (Hmax + Hmin) / 2 * L = volume, m3
where, W- Width, AT- Height, D- Length
If it is visually visible that the wood is fresh and, accordingly, damp (humidity above 20%), then the seller is obliged to reduce the total volume by multiplying the received cubic capacity by the coefficient:
- 0,96 for softwood
- 0,95 for deciduous.
Sampling method used to determine the volume of a large batch of unedged lumber. When loading, for example, into the body of a vehicle, every fifth, tenth or twentieth board is measured using the second method.
The resulting volume is multiplied by five, ten, twenty. Loading continues to the next control board. The selection of control boards in a separate foot is also practiced. The calculation is made after the loading is completed.
Calculating the volume of a bar: how much is a bar in a cube?

The beam differs from the edged board only in that all its faces or two opposite ones have the same size: more than 0.05 m in thickness and 0.013 m in width. The formula for determining its volume is standard

W * T * D = volume of timber, m3.
To find out how much timber is in one cube
1 / (W * T * D) = amount of timber in 1 m3 (cube)
where, W- Width, T- thickness, D- Length
Translation: 1mm=0.001m, 10mm=0.01m, 100mm=0.1m
When buying a beam, the volume must be determined by the piece, since the beam is laid with spacers in the stack. The measurements of such a stack and the calculation of the cubature according to the above formula invariably lead to a significant overestimation of the volume.
Length of 1 cube of timber (and any edged lumber) in meters is determined by dividing the unit by thickness and width. For example, you need to find out how much timber is in one cube - a face of 180 mm.
1 / (0.18 * 0.18) = 30 meters 87 cm.
1 meter of such a bar will have the following volume.
0.18 * 0.18 * 1 = 0.0324 m3.
These calculations may be needed when determining the cost of funds and material.
Construction log volume: how many logs are in one cube?
How many logs in one cube: calculation - Photo
Log buildings are and will be relevant. The determination of the volume of round material depends on the method of its production.
- Construction log of manual debarking.
- Construction log, rounded on special machines.
The section of the barrel for trimming by hand has the shape of a slightly truncated cone, so the cylinder volume formula is used, but with some peculiarities.
3.14 * r 2 * L = log volume, m3
Here
r- average radius, calculated as (r 1 + r 2) / 2, r 1 - radius from one end of the log, r 2 - radius from the other end of the log.
L- log length.
3,14
- constant "Pi".
The rounded log has, of course, a cylindrical shape and is calculated according to the above formula. But here the radius is measured at any end once. Determining the number of logs in 1 cube is determined similarly to a bar.
1 / (3.14*r2 * L) = Number of logs in 1m3 (cube)
Blanks for construction logs are measured in the same way.
The radius (diameter divided in half) is measured without taking into account the thickness of the tree bark. In practice, manual calculations are not carried out. They use special tables summarized in a cubature book. They are also available in electronic form.
In conclusion, it should be noted that lumber for critical work, standard in size, wood species and humidity, should be purchased at large sites. A small manufacturer, as a rule, is not allowed there due to the lack of appropriate control over the quality of their products.
