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

the answer is

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