A right rectangular prism looks like a rectangular shoe box. It has 6 faces, all of which are rectangles. The formula for its volume is
V = whl, where w=width, h=height and l=length
From the statement of the problem:
h = 3w
l = 2w
Since all are in terms of w already, the volume could be expressed as a function of the width.
V = w × 3w × 2w
[tex]V=6 w^{3} [/tex]
