Question

A large game cube with a four-inch side length is wrapped with shrink wrap. How many square inches of shrink wrap will be used to wrap nine game cubes?

Answer 1

Answer:

864 square inches

Step-by-step explanation:

To solve this problem, first we need to know the area of each side of the cube(since the shrink wrap will cover these sides) :

The area of each side is A=$L^{2}$ where L is the length of the side. In this case, L= 4 inches.

Thus, the area of each side is $A=L^{2}=4^{2} =16$ square inches.

However, the cube has 6 sides so we have to multiply the area of each side by 6, this gives us $(16)(6)= 96$ square inches. Thus, we need 96 square inches of shrink wrap for each cube.

Now, we have nine cubes, so we have to multiply those 96 square inches by 9, $(96)(9)= 864$.

Thus, we need 864 square inches of shrink wrap to wrap 9 cubes.
