Question

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

Answer 1

Answer:

The  surface area of the square prism is $104\ cm^{2}$

Step-by-step 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

$SA=2(2)^{2} +4(2)(12)=104\ cm^{2}$
