Question

The dimensions of a square prism are 2 centimeters by 2 centimeters by 12 centimeters. What is its surface area?

Answer 1

The surface area of the square prism is
`104\ cm^(2)`

Explanation:

we know that

The surface area of the square prism is equal to

`SA=2b^(2) +4bh`

where

b is the length side of the square base

h is the height of the prism

In this problem we have

`b=2\ cm`

`h=12\ cm`

substitute

`SA=2(2)^(2) +4(2)(12)=104\ cm^(2)`
