Question

Kira decorates the exterior faces of a gift box in the shape of a cube .What is the surface area in square inches of the gift box that Kira decorates?

Answer 1

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

$SA=6(6.5)^{2}$

$SA=253.5\ in^{2}$
