You buy shingles by the square. Three bundles cover one square. A square is 10x10. So four bundles should be more than enough.
Standard fiberglass shingles come 3 bundles to the square.
26 bundles should be about right.

100 square feet is called a 'square'. Given that, you roof is 36 'squares'. Shingle coverage for 20, 25, and 30 year shingles is 3 bundles per square. 40 and 50 year shingles are 4 bundles per square. Say the shingle you select has a coverage of 3 bundles per sqaure: the number of bundles you need would be 3 * 36, plus the amount for caps (which cover the 'peaks' and 'hips' in your roof. To estimate the amount of bundles you need for peaks, assume one bundle for every 25 feet of 'hip' or 'peak' you need to cover.
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!

3 bundles to a square and 100 sq. ft. in a square, so 3 times 16 equals 48. Depending on how much roof edge and peak add a couple bundles for starter strip and the cap.
One bundle of shingle covers about 33 square feet of roof hence around 850 bundles of shingles will be needed for 28000 square feet roof!
3 3/4 squares.
4 bundles for 15 year. 3 bundles for 25 year.
