Let's say you have calculated that for the construction you need 40 boards with a length of 6 m, width 150 mm, thickness 40 mm. Put all these values are in meters and multiply:

40х6х0,15х0,04=1,44, where 40 is the number of boards; 6 – length of the Board; 0,15 – Board width; 0,04 – Board thickness.

Finally got a 1.44 cubic meters, nearly half a cubic meter.

40х6х0,15х0,04=1,44, where 40 is the number of boards; 6 – length of the Board; 0,15 – Board width; 0,04 – Board thickness.

Finally got a 1.44 cubic meters, nearly half a cubic meter.

The same method calculate how many boards will be in one cubic meter: divide the cubic meter by the volume of one Board. For our example, in which the Board thickness of 40 mm, a width of 150 mm and a length of 6 m, the calculation would be:

1/0,04/0,15/6=27,7777.

This means that in one cubic meter can hold about 28 of the required boards.

1/0,04/0,15/6=27,7777.

This means that in one cubic meter can hold about 28 of the required boards.

The above calculation is suitable for lumber and trim boards. To calculate the number of required lining, unedged boards and other lumber will have a little differently – you will need a table to calculate the cubic content of timber.

Note

Consider the calculations that if you leave lumber sellers often try to round values square footage is not in your favor.
