Hi
calculation for the swimming pool would be
length in feet x width in feet x depth in feet x 6.25 = gallons capacity
15,000
42
10,000 to 11,000 gal.
A round swimming pool 12 feet across by 4 feet deep will hold 452 ft3 which converts to 3,381 gallons
1-2 gallons of muriatic acid will break down the buffer solution(alkalinity in the water). Will then probably have to raise pH back up
13 x 21 x 4 = 1,092 cubic feet = 8,168.7 gallons (rounded)
Call your local water company.
12ft by 21ft is equal to 4m by 7m or 28 square meters.
No. Seven yards equal 21ft. 1 yd = 3 ft 7yd x 3ft/yd = 21ft
640.08 cm
3780lbs
21 feet is 7 yards.
21 feet = 6.4008 metres
