A box has a volume of 128 feet. The length is twice the width and the height is the same as the width. What are the dimensions of the box?

Answer: width = 4 ft, length = 8 ft, height = 4 ft

Step-by-step explanation:

width (w) : w

length (L) : 2w

height (h) : w

Volume (V) = w * L * h

128 = w (2w) (w)

128 = 2w³

64 = w³

∛64 = ∛w³

4 = w

width (w) : w = 4

length (L) : 2w = 2 (4) = 8

height (h) : w = 4
