Answer 12

If you have the size/cost/measure of one item, and you need the size/cost/measure of many similar items, you multiply. This was the case here.

Answer 13

When you are given the size/cost/measure of many items, and the size/cost/measure of 1 item, and you are asked how many items, you divide.

Answer 14

Ok...Makes sense.
