A "square" of shingles is enough to cover 100 sq ft of roof. Shingles
usually come

I must be losing it. 8' x 12' = 96 sq ft which says that one "square"
of shingles is all you ned. That can't be right as the normal 3
bundles of shingles is not going to cover that much roof.

Where is my error???

in 3 bundles per square.

I don't think you have an error, but is that 8 x 12 the size of the shed or
the actual size of the roof ? Then you have to allow a few extra for the
bottom run and the ridge cap.
