Question

A container in the shape of a rectangular prism has a height of 3 feet. Its length is three times its width. The volume

of the container is 324 cubic feet. Find the length and width of the container.

length=_____ feet

and width=___
feet

Answer 1

Answer: Width = 6 ft, length = 18 ft

Explanation:

If the width is w, then the length would be 3w.

3 * 3w * w = 324

9w^2 = 324

w^2 = 36, since w is positive it has to be 6.

So, the width = 6 and the length = 18.
