Question:

A stack of lumber is 6-feet high. If each piece of lumber is 4-inches thick, how many pieces of lumber are in the stack?

A 18
explanation

Multiply the height of the stack in feet by 12 to determine the height of the stack in inches: 6 × 12 = 72 inches. Divide that number by 4 inches, the thickness of each board to determine the number of pieces of lumber in the stack: 72 ÷ 4 = 18.

This is really helping me study for my asvab. I may be in 9th grade but it’s a lot of help on learning new things to get to a goal that has been set since I was 5. I love this app.
