Answer:

There are 88 square inches needed to cover a box that is 4 in • 6 in • 2 in

Explanation:

In order to cover the box you need to find the surface area of it. The formula for finding the surface area of a rectangular prism is 2 • ((w•l) + (h•l) + (h•w)). The dimensions of the box is 4 inches in length, 6 inches in width, and 2 inches in height.

1. Apply the dimensions into the formula of the rectangular prism when the numbers are plugged in it results in 2 ( (6•4) + (2•4) + (2•6) )
2. Multiply the dimensions the area of length• width is 24 (six times four is twenty-four), the area of height•width is 8 (two times four is eight), and the area of height•width is 12 (two times six is twelve). At the end of this step it becomes 2 • ((24) + (8) + (12))
3. Add all the numbers inside the parentheses then it becomes 2 • (44)
4. Multiply the number in parentheses by 2 the final answer is 88 in²
