You can look at calculista's answer to see how it is solved :)

Answer 2

`2,124\ in^(2)`

Explanation:

we know that

The surface area of a rectangular prism is equal to

`SA=2B+Ph`

where

B is the area of the base

P is the perimeter of the base

h is the height

In this problem we have

`B=18*24=432\ in^(2)`

`P=2(18+24)=84\ in`

`h=15\ in`

substitute

`SA=2(432)+(84)(15)=2,124\ in^(2)`
