Question 200117
Volume for a cubic shape is given by {{{Volume =Width*depth*height}}}
You are given a volume in cubic feet -- but dimensions in inches. So first, convert the volume to cubic inches.

{{{Volume[feet] *12*12*12= Volume[inches]}}}
{{{25920 = Volume[inches]}}}
{{{25920 = Width*depth*height}}}
{{{25920 = 18*depth*24}}}
{{{25920/(18*24) = depth}}}
{{{60 = depth}}}
The cabinet must be 5 feet deep
