How many 10x10 areas are in 4000 square feet?
There need not be any as an area can have any shape; for example 4000 sq ft can be a rectangle with side lengths 1 ft and 4000 ft - as this rectangle has a width of 1 ft a 10 ft by 10 ft area cannot be extracted from it. However, if you are asking how many sections with the same area as a square of sides 10 ft can be made in an area of 4000 sq ft, then: 4000 sq ft ÷ (10 ft × 10 ft) = 4000 sq ft ÷ 100 sq ft = 40.
How many gallons of water does a 3 quarter acre pond have that is 6 foot deep?
1 acre = 43,560 sq ft → volume pond (liquid) = 3/4 x 43,560 sq ft x 6 ft = 196,020 cu ft * In UK: 196,020 cu ft ≈ 1,220,976 imp gal * In US: 196,020 cu ft ≈ 1,466,331 US gal
How much area will a 50 pound bag of sand cover at 2 inches thick?
50 pounds @ 100 pounds / cu ft = 0.5 cu ft = 864 cu ins So : sq root (864 / 2) = 20.785 inches So: will cover a square of 20.785 ins * 20.785 ins ( 1.732 ft * 1.732 ft) 2.999 sq feet area each bag (say 3 sq ft)
How many cubic feet are need to cover 110 square feet 3 inches deep?
Convert the inches to feet and work out the volume of the cuboid with base area 110 sq ft and height of 3 inches: 12 in = 1 ft → volume = 110 sq ft x 3 in = 110 sq ft x 3/12 ft = 27 ½ cu ft (= 27.5 cu ft)
How many 50 lb sand bags would you need to cover 400 sq ft 1 inch deep?
