How many square feet of wrapping paper do you need . To wrap a package it is 3.5 feet long 18 inches wide and 2 feet high

2 answers

there are 3 pairs of faces, each a rectangle. So, the area is

2(3.5*1.5 + 3.5*2 + 1.5*2)

Of course, that does not include any overlap for taping things shut...
L = 3.5 Ft.
W = 18 1n. = 1.5 Ft.
h = 2 Ft.

As = 2(W*h) + 2(L*h) + 2(L*W).
As = Surface area.
