There are 27 shingles per bundle with the in/ft system, three bundles per roofing square, or 100 sq. ft. You have to consider exposure, not actual size. Exposure is 5 inches so you have 5 x 36 inches =180 sq. Inches divided into 14,400 sq. inches (120 x 120) = 80 shingles divided by three = 26.66 shingles per bundle. The mfgr rounds it up to 27. I carried, opened, and nailed enough bundles to know.
I am not positive but if it is in a package of 235 i am pretty sure it is 235!
