A gift box measures 14 inches by 12 inches by 6 inches. How much wrapping paper is needed to exactly cover the box?

This is find the surfae area

with some logic and simplifiaction we get

SA=2 (LW+LH+WH)

lw means legnth times width

lh means legnth times height

wh=width times height

L=14

W=12

H=6

(It doesn't matter which is which when working with this shape)

SA=2 (14*12+14*6*12*6)

SA=2 (168+84+72)

SA=2 (324)

SA=648

answer is 648 in^2

Surface Area = 648 inches
