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???
about 60 60lb bags
about 60 60lb bags
15.21 cubic yards 1369 40lb bags 913 60lb bags and only 685 of the 80lb bags.
50lb bags 3.7 60lb bags 3.1 80lb bags 2.3 90lb bags 2.1 These amounts are for using the redi-mix bags.
According to the FAQ on the Sakrete web site, Sixty of their sixty pound bags of High Strength concrete mix will be required to make a cubic yard of concrete.
10 bags will give you 6'2/3", seven bags will give you 11 bags will give you 7'1/3". Each bag is 2/3 cu feet.

Approximately 3 bags of 0.8 cubic feet of rubber mulch are needed to cover an area of 105 square feet that is 1 inch thick.
It would depend on what size of bag, 60lb or 80lb.one 60lb bag usually yeilds about 0.45 cubic feet once mixed (this will vary slightly depending on how much water you add). So 42 bags times 0.45 cubic feet equals 18.9 cubic feet. there are 27 cubic feet in a cubic yard, so divide 18.9 by 27 and you get about0.7 cubic yards.if you had 42 bags that weighed 80lbs. then you'd have about 25.2 cubic feet or about0.93 cubic yards
You would need 31, 80 pound bags to cover 1 cubic yard at 4 inches deep. If you would like the depth to be 6 inches, 45 bags would be needed.
The answer depends on the depth to which you wish to cover it.
Depends what is in the bags..... Also cubic meter, yard, inch, etc.
