Answer:
l = 6 inches
Explanation:
We have,
The volume of a rectangular prism with a square base is
.
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* b* h](https://img.qammunity.org/2021/formulas/physics/college/ocyw8u5lwxlyszjwkcyg56iaucyxjs14q4.png)
A is area of base of prism
It has a square base, l =b
![V=l^2* h\\\\l=\sqrt{(V)/(h)} \\\\l=\sqrt{(180)/(5)} \\\\l=6\ in](https://img.qammunity.org/2021/formulas/mathematics/high-school/jgwfykoz2l0eetn16d4ow60kzsvy2o5yqn.png)
So, the length of the edge of the square base is 6 inches.
