Answer:

The surface area of the gift box that Kira decorates is 253.5\ in^{2}

Step-by-step 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}
