The prism has a surface area of 202 ft2.What would the surface area of the prism be if each dimension were tripled?

ft2

Answers

Answer 1

Answer: Let's call the dimensions of the prism (I will assume it is rectangular) a, b, and c.

The surface area is:

$2ab + 2ac + 2bc = 202$

The dimensions of the new prism are 3a, 3b, and 3c.

This surface area would be:

$2(3a)(3b) + 2(3a)(3c) + 2(3b)(3c) =$

$2(9ab) + 2(9ac) + 2(9bc) =$

$9(2ab + 2ac + 2bc) =$

$9(202) = \boxed{1818}$

Hope this helps :D
