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.
