shall assume the 18ft measurement is the diameter, not radius. 18ft = 5.486m = diameter 52in = 1.321m = depth pi x radius(squared) = area of the circle pi x 2.243(squared) = 15.8055 meters squared area x depth = volume in meters cubed 15.8055 x 1.321 = 20.879 meters cubed 1 meter cubed = 1000L 20.879 meters cubed = 20879L 20879L is: 5515.648 US Gallons 4592.738 UK Gallons
A sphere volume = 4/3 pi r cubed
1409.23 gallons. Assuming that your pond is a cylinder shaped pond, then the formula pi * radius squared * height would work in this situation. 20 inch= 1.66 feet = height. pi * 6 feet squared * 1.66 feet = 188.4 feet cubed. 1 foot cubed = 7.48 gallons roughly. 188.4 * 7.48 = 1409.23.
To calculate the volume, you have to cube the length of its side. In this case, 11 cubed.

0.81 meters cubed per minute equates to 214 (or 213.979362) US gallons per minute.
Multiply length by width by height to get volume, then convert to gallons. 216000 in cubed is 935.1 gallons
4710 inches cubed equates to 20.4 (20.38961) US gallons of water.
1 m3 = 264.172 gallons.
7,481 liquid gallons or 6,429 dry gallons.
Conversion: cm cubed per minute x 1.67 × 10^-8 = cubic meters per second.
There are 0.000000000264172 gallons in one billion cubic microns.
One would need a third measurement, height, in order to calculate volume. lwh, or length x width x height equals volume in gallons-cubed.
There are 7,985.76 gallons of water in a 1799.5 cubic feet pool.
248,832 cubic inches = about 897 (896.951935) Imperial gallons.
