the volume V of a rectangular prism is given by V=lwh, where l is the length of the prism, w is it's width, and h is its height. The length of a certain rectangular prism is three times its width, and its height is 2 feet less than its width. write a simplified expression that represents the volume of the prism in cubic feet

since 1 ft is 12 in. multiply V=lwh with 12 in. then divide it with w 3 times each feet then you will find the rest easy.
