Answer:

$84\text{ in}^2$ .

Step-by-step explanation:

We have been given that Mrs. Chen's students are making and decorating gift boxes for a nursing home. The boxes are 7 inches wide, 7 inches long, and 7 inches high. We are asked to find the amount of cardboard that is needed for each box.

We will use surface area of cuboid formula to solve our given problem.

$SA=2(lw+lh+hw)$ , where,

l = Length,

w = Width,

h = Height

$SA=2(7\text{ in}\cdot7\text{ in} +7\text{ in}\cdot7\text{ in}+7\text{ in}\cdot7\text{ in})$

$SA=2(14\text{ in}^2+14\text{ in}^2+14\text{ in}^2)$

$SA=2(42\text{ in}^2)$

$SA=84\text{ in}^2$

Therefore, Mrs Chen needs 84 square inches of cardboard.
