When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab.
One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.
9 bundles assuming std. 3 bundle/sq. shingles
A 'bundle' is an arbitrary amount - Usually we talk about 'squares' in roofing. One 'square' is 100 square feet

3 bundles makes one sq
typically a square is three bundles (about 26 shingles per) but in some types of architectural shingles there are four bundles per square to make them easier to handle.

Not sure, but one bundle covers 33.33 square feet. 3 bundles to a square.
20 squares or 60 bundles
3 bundles makes one sq
3 bundles = 1 square 10 2/3 sq x 3 bundles = 32 bundles
Roofing shingles are measured in "squares". One square is 100 square feet. *ASSUMING YOUR ROOF IS FLAT OR NEARLY FLAT* 16' x 80' = 1280 square feet. You'll need 12.8 (or 13) squares of roofing shingles. The majority of roofing shingle bundles are 3 bundles per square. 13 squares times 3 bundles per square = 39 bundles (minimum). Good luck!
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.

There are 3 bundles of conventional shingles to a square, so 3 X 27
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
