plzz just give me a formula or something to help me figure it out.thxx

Answer 1

volume = length x width x height

length 2 ft=24 inches

width 4 ft = 48 inches

ht = 8 inches

volume=24 x 48 x 8 = 9216 cu. inches

Answer 2

2 ft = 24 in

4 ft = 48 in

8 in = 8 in

24 x 48 x 8 = 9216 in³

D. is your answer.

Answer 3

Easy just convert all of your dimensions to inches and multiply it together so you have:

24 inches wide, 48 inches long, and 8 inches deep

All multiplied together = 9216 cubic inches

Answer 4

Make the feet into inches, then multiply all three numbers. However, I won't give you the answer since you only wanted to know how to do it.
