Question

you need gi wrap a Christmas present for your friend. the box the gift is in has a length of 12 inches, a width of 8 inches, and a height of 7 inches how much wrapping paper do we need

Answer 1

The given problem can be exemplified in the following diagram:

The amount of paper needed to wrap the box is equivalent to the surface area of the box.. the surface area is equivalent to the sum of the areas of each face. Therefore, the surface area is:

`A=2(12)(7)+2(8)(7)+2(12)(8)`

Each term is multiplied by two representing the two faces of the corresponding area:

Solving the operations:

`A=472`

Therefore, 472 square inches of wrapping paper is needed.
