Question

Find the total area of the prism.

144 sq. in.
576 sq. in.
864 sq. in.

Answer 1

864 sq. in

This is for total Area not lateral area.

Answer 2

`864\ in^(2)`

Explanation:

The figure is a cube

The surface area of a cube is equal to

`S=6b^(2)`

where

b is the length side of the cube

In this problem we have

`b=12\ in`

substitute

`S=6(12^(2))=864\ in^(2)`
