Rebecca gives gifts to 12 employees. Each gift is in a box that is 12 inches by 10 inches by 3 inches. How much wrapping paper does Rebecca need to completely the cover the boxes?

F. 360 in(insert exponent 2)
G. 1,720 in(insert exponent 2)
H. 4,320 in(insert exponent 2)
J. 14,400 in(insert exponent 2)

surface area of 1 box

= 2(12x10) + 2(12x3) + 2(10x3)
= 372 in^2 for 1 box
But she has 12 of these
total surface area = 4464 in^2

Silly question, no allowance is made for obvious overlap of the paper.
none of the answers match anyway.

To find the amount of wrapping paper needed to cover the boxes, we first need to calculate the surface area of each box. The surface area of a rectangular box is found by adding up the areas of all of its six faces.

Given that the dimensions of each box are 12 inches by 10 inches by 3 inches, we can calculate the surface area as follows:

1. Two sides have dimensions 12 inches by 10 inches, so their combined area is 12 inches * 10 inches = 120 square inches.

2. Two sides have dimensions 12 inches by 3 inches, so their combined area is 12 inches * 3 inches = 36 square inches.

3. Two sides have dimensions 10 inches by 3 inches, so their combined area is 10 inches * 3 inches = 30 square inches.

Now, to calculate the total surface area of one box, we add up the areas of all six faces:

120 square inches + 120 square inches + 36 square inches + 36 square inches + 30 square inches + 30 square inches = 372 square inches.

Since Rebecca has 12 boxes, we multiply the surface area of one box by the number of boxes:

372 square inches * 12 = 4,464 square inches.

Therefore, Rebecca needs 4,464 square inches of wrapping paper to completely cover the boxes, which is not one of the given options.
