How many litres water in 18ft pool?
That would depend what shape and how deep the pool is.
If it is a round pool, 18 feet across and 4 feet deep, you would have 1000 cubic feet (pi R squared D), which is 28,300 liters.
How many liters of water are in a swimming pool 25 meters by 9 meters which is 1.8 meters at the deep end and 1 meter at the shallow end?
How do you figure out how much water it takes to fill a swimming pool that is 18 feet round and 4 feet deep?
It's a perfect circle? Is it 18ft across or 18ft around the edge? If it is 18ft across then the radius is 9 feet and the volume (amount of water needed) is going to be (pi)x (r squared)= 81pi which is about 254.469 square feet x 4 feet in height = 1018 cubic feet. A cubic foot is about 7.5 gallons so you need 7634 gallons of water to fill your pool. If it is…
