How many bundles of 3-Tab Shingles are needed to cover 80 square feet?
26 bundles should be about right.
9 bundles assuming std. 3 bundle/sq. shingles
How much area would 15 bundles of shingles cover. Standard duty shingles use 3 bundles for every 100 square feet so 15 bundles would cover 500 square feet.
54
A bundle of Shingles will cover roughly 33 square feet. A square of Shingles (3 Bundles) will cover 100 square feet.
i think it should take 7 bundles
5.85 squares + 15% waste = ~6.75 squares of material needed 1/3 square per bundle of shingles 20 - 21 bundles of shingles (buy 21 and return the extra if necessary - it's i'mportant to have shingles from the same pallet/factory for matching purposes.

4 bundles of shingles covers 100sq.ft. of course this is approx. shingles come in several sizes and then you must allow for waste cuts etc
If your shingles say they cover 3 bundles to a square ( 10'x10' or 100 sq. ft) then one and a half. Some thicker, heavier shingles are 4 bundles to a square so you'd need 2.
3 3/4 squares.
