Gekata [30.6K]

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

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

$SA=253.5\ in^{2}$

A rectangle has an area of 72 in². The length and the width of the rectangle are changed by a scale factor of 3.5.

Ira Lisetskai [31]

For this problem, it can be solved by forming two equations. The first equation is the area of the original rectangle. Let l be the length and w be the width. l x w = 72 will be 1st equation. Then, the 2nd equation is 3.5l * 3.5w = A. By substitution, the new area, A = 12.25( l x w) = 12.25 (72) = 882 in<span>².</span>
