Board feet is a measurement of lumber volume. A board foot is equal to 144 in3 of wood. About how many board feet is a piece of lumber that measures 2 in. by 8 in. by 12 ft?

Question

6.5 board feet

1.3 board feet

22 board feet

16 board feet

Answer 1

The volume of the piece of lumber can be calculated by multiplying the dimensions together and converting to cubic inches:

2 in x 8 in x 12 ft x 12 in/ft = 2304 cubic inches

Then, to convert to board feet, divide by 144:

2304 cubic inches / 144 in3/board foot = 16 board feet

Therefore, the piece of lumber measures 16 board feet.
