23 gallons

Explanation:

Given:

A barn is shaped like a rectangular prism with a triangular prism on top as shown.

The exterior four walls and two triangular faces need to be repainted.

To Find:

If one gallon of paint covers 232 square feet, how many gallons will it take to repaint the barn?

Solve:

`12\cdot38/2\cdot2+84\cdot20+38\cdot20\cdot2`

=
`5336\;square\;feet`

`(5336)/(232)=23`

Hence 23 gallons to repaint the barn
