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
