Answer:
The height of the box is (F) 8 ft.
Explanation:
We know that a wooden box has a square base and that the height is 2 times the length of one side of the base. That can either be the length or the width of the box. The volume of the box is 128 cubic feet.
We're asked to find the height of the box.
Volume = l · w · h
128 = l · w · height which is twice the length of either the width or the length
but since it's a square base, it doesn't matter which side is the height twice of
128 ÷ 2 = 64
= 4
4 × 4 = 16
128 ÷ 16 = 8
Length = 4, Width = 4 and height = 8
