First calculate cubic ft.
10ft x 15ft x 3.5ft = 525 cubic ft.
Convert cubic ft to gallons.
1 Cubic Foot = 7.48 US gallons
525 cubic ft x 7.48 gallons/cubic ft = 3927 gallons
598 Imperial gallons, approx.
96 cubic feet will hold a little over 718 gallons
If the surface is 9-ft by 16-ft, and the sides are straight all the way down,then the amount of water in it is 1,077.2 gallons for every 1 foot of depth.
1234.29 gallons of water
This pond can hold up to 1,346,493.51 gallons of water.
A pond this size holds up to about 1,955,108 gallons of water.
598 Imperial gallons, approx.
96 cubic feet will hold a little over 718 gallons
This pond can hold up to 1,436.26 gallons of water.
1.5x4x6x7.48 gallons/cubic foot=269.28 us gallons
This pond can hold up to 533 gallons of water.
Years ago we had some ponds put in so because of the time lapse my answer may not be exact. I believe the formula was as follows: 1 acre of water that is 1 foot deep equals about 300,000 gallons of water. That would make your pond about 31 gallons.
This size pond can hold up to 2,992.21 gallons of water.
This size pond will hold up to 897.7 gallons of water.
A maximum of 1,651.7 gallons.
This pond can hold up to 201,974 gallons of water.
