Wrapping a `4''*4''*3''` pack requires $0.25 worth of wrapping paper. $0.18 for ribbon and $0.12 for the bow.

The surface area of the box is 80 square inches. The length of the ribbon required assuming it is wrapped along the center of all the sides is 2*(4 + 4 +3) = 22 inches.

For the pack with dimensions `8''*8''*6''` , the area of paper required is 320 square inches. The cost of the paper is 100 cents. The length of the ribbon required is 44 inches. The cost of the ribbon is 36 cents. As the box is twice as large it is assumed that the bow is also made twice as large and costs 24 cents.

**The total cost of packaging is 160 cents.**

Somehow the answer is actually 148 cents. Can you help me derive it?
