The roof of the house down the road is in the shape of a square pyramid. The length from the gutter to the top is 15 feet and the length of the gutter on one side is 18 feet with no overlap. One bundle of roof shingles covers 25 square feet. How many bundles should you buy to cover the roof?

so you have 4 triangular faces, with
base = 18
height = 15
(4 * 18*15/2)/25 = 21.6
so, buy 22 bundles
maybe 23, if the scraps cannot be used.
