Question

How many square inches of paper did Benjamin use to wrap the box

Answer 1

Answer:

$2,124\ in^{2}$

Step-by-step 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

$SA=2(432)+(84)(15)=2,124\ in^{2}$
