1 acre = 43,560 square feet At 1/2-ft deep, that's (43,560 x 1/2) = 21,780 cubic feet 27 cubic feet = 1 cubic yard 21,780 cubic feet = 806 2/3 cubic yards
1 acre is 6,272,640 square inches. Since you want to cover it one inch deep you need 6,272,640 cubic inches of water. There are 231 cubic inches in a gallon. So divide 6,272,640 by 231 and you get 27,154.2857 gallons! HOWEVER: If you want to save water, consider this: When water freezes, it increases in volume about 9%. So if you used ICE to cover your acre and only needed the ice to be 1 inch deep, you could use 9% less water to start with! (I'll let you do the math on that.) Ice is still water, so unless you are asked to use LIQUID water this question has 2 answers.
You would need 31.88 cubic yards of topsoil to cover 855 sq feet at 6 inches deep.
How deep do you want that ?If you want it 1.6 inches deep, then it can cover 1 square foot.If you want it 10-ft deep, then it can't cover that much area.
Although the answer seems completely useless, this is a nice little arithmetic problem. 1 foot = 12 inches 1 cubic foot = (12 x 12 x 12) = 1,728 cubic inches 1 acre = 43,560 square feet 1 acre, 1 foot deep = (43,560 x 1 x 1,728) = 75,271,680cubic inches ======================================= -- Take the number of cubic inches. -- Divide it by 75,271,680. -- The answer is the number if acre feet.

Well, an acre is 43,560 sq. feet. One inch is 1/12 feet so one acre of water 1 inch deep is43560 1/12 = 3630 cubic feet of water.There are 231 cubic inches in an American gallon. A cubic foot is 12 inches by 12 inches by 12 inches and thus one cubic foot is 12 12 12 = 1728 cubic inchesso 3630 cubic feet is 3630 728 = 6272640 cubic inches. Thus the amount of water needed to cover one acre to a depth of 1 inch is 6272640/231 = 27154.3 gallons.
