Answer 2

The surface area of the gift box that Kira decorates is
`253.5\ in^(2)`

Explanation:

see the attached figure to better understand the problem

we know that

A cube has six square faces

The surface area of a cube is equal to the area of the six squares faces

`SA=6b^(2)`

where

b is the length side of a cube

In this problem we have

`b=6.5\ in`

substitute

`SA=6(6.5)^(2)`

`SA=253.5\ in^(2)`
