dybincka [34]

we know that

The surface area of a cube is equal to

$S=6*A$

where

A is the area of one face of the cube

in this problem

$A=8.5^{2}= 72.25\ in ^{2}$

Find the surface area

$S=6*72.25=433.5\ in ^{2}$

therefore

<u>the answer is</u>

$433.5\ in ^{2}$ of wrapping paper is needed to cover the box completely
