We have,

The volume of a rectangular prism with a square base is 180\ in^3.

Height of the prism is  5 in

It is required to find the length of the edge of the square base. Let it is l.

The formula of the volume of the rectangular prism is given by :

V=l\times b\times h

A is area of base of prism

It has a square base, l =b

V=l^2\times h\\\\l=\sqrt{\dfrac{V}{h}} \\\\l=\sqrt{\dfrac{180}{5}} \\\\l=6\ in

So, the length of the  edge of the square base is 6 inches.
