Answer:
The surface area of the gift box that Kira decorates is [tex]253.5\ in^{2}[/tex]
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
[tex]SA=6b^{2}[/tex]
where
b is the length side of a cube
In this problem we have
[tex]b=6.5\ in[/tex]
substitute
[tex]SA=6(6.5)^{2}[/tex]
[tex]SA=253.5\ in^{2}[/tex]
