The length of a rectangular prism is four times the height of the prism and one-third the width of the prism.
If the volume of the prism is 384in3, what is the width of the prism?

정답:

24
Explanation/Reference:
If the height of the prism is h, then the length of the prism is four times that, 4h. The length is one-third of
the width, so the width is three times the length: 12h. The volume of the prism is equal to its length
multiplied by its width multiplied by its height:

The height of the prism is 2 in, the length of the prism is (2 in)(4) = 8 in, and the width of the prism is (8 in)
(3) = 24 in.
