9x9, 81x1, 3x27, 162x.5 , etc.
I am not sure if you mean 3(27) or 3(27x), either way the answer would be 81 [if you are referring to 27x, then just simply add an x to the end of 81.]
1x81 or vice versa 3x27 or vice versa 9x9 Those are the factors that make up 81 - 1, 81, 3, 27, and 9 - (I'll let you be the judge on which are the first 4)

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!
81, as it is the highest factor of 81 (81 and 1) and is also a factor of 162 (81 and 2)
To convert cubic feet to cubic yards, divide by 27. If each bag is 2 cubic feet, then 1 cubic yard is equivalent to 13.5 bags of mulch (27 cubic feet ÷ 2 cubic feet per bag). Therefore, 6 cubic yards are equivalent to 81 bags of mulch (6 cubic yards * 13.5 bags per cubic yard).
