Answers:    28
calculates out to be 39, assuming the 28 x32 is the horizontal footprint of the building and does not even so include the overhangs. The third side of a 5/12 slope is 13. So 13/12 times the horizontal total area. example: (28+4)x(32+4)x13/12. Each 4x8 sheet of sheathing is 32 sf. 41 sheets will be needed if your rafter are laid out right and you don't have to chop up any sheets and you lone want to use milled edges to milled edges on the top course. You could make 39 sheets work.
