A wood deck surface has 320 sf of coverage. Boards have a 5-1/2 in. actual face width, and the order includes an 8 percent cutting allowance. What linear footage is closest?
Correct Answer
D) 754 lf
Linear footage before allowance is 320 x 12 / 5.5 = 698.2 lf. Adding 8 percent gives 698.2 x 1.08 = 754.1 lf, or about 754 lf. Other choices omit the allowance, use a 6 in. face width, or add too much material.
