Question

Bella is wrapping a cube-shaped gift box that measures 8.5 inches along each edge. How many square inches of wrapping paper is needed to cover the box completely without overlapping?

Answer 1

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
