Final answer:
To cover a rectangle gift box with dimensions of 8 inches by 10 inches by 7 inches, you need to calculate the surface area by adding the area of all six faces. After calculation, you would need 412 square inches of wrapping paper.
Step-by-step explanation:
To calculate how much wrapping paper is needed to cover a rectangle gift box exactly, we need to find the surface area of the box. The box dimensions are 8 inches wide, 10 inches long, and 7 inches tall.
Surface area of a rectangle box is calculated by adding the areas of all six faces. The areas of the faces are:
Calculating each area:
Adding all of these areas together gives us:
160 in² + 112 in² + 140 in² = 412 in².
Therefore, you would need 412 square inches of wrapping paper to cover the box exactly.
