Unfinished lumber is sold in units called board feet. a board foot is the volume of lumber contained in a board 1in thick 1foot wide and 1 foot long. how many cubic inches of wood at in 1 board foot?

Hello!

The volume of a board foot can be calculated using the following formula:

volume = (length) x (width) x (depth)

We know that there are 12 inches to every foot. Therefore, the dimensions of a board foot can be restated and inserted into the above formula:

volume = (1 ft) x (1 ft) x (1 in)
volume = (12 in) x (12 in) x (1 in)

Simplify the right side of the equation:

volume = 144 in

We have now proven the volume of a board foot to contain 144 cubic inches of wood.

I hope this helps!
