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

864 square inches

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.
