5 and a bit ;)
1 ft = 12 in → 1 in = 1/12 ft Volume required to cover is 90 sq ft × 1 in = 90 sq ft × 1/12 ft = 7.5 cu ft → number of bags = 7.5 cu ft ÷ 0.8 cu ft/bag = 9.375 bags → you need to buy 10 bags
The volume of 36ft2 to a depth of 6" = 1/2ft is 36ft2 x 1/2ft = 18ft3. Each bag contains 5ft3 so 18/5 = 3.6 bags are needed to cover the area, so 4 bags would have to be purchased, with 2/5 bag left over.
to what depth???
12
