A "cubic water" is not a measurement unit!
There are 219.969 Imperial gallons of water per cubic meter.
There are 7.48052 US gallons per cubic foot.
My guess would be 7.48 gallons since that is how many gallons of water is in a cubic foot
(237 cubic feet) x (1,728 cubic inches per cubic foot) / (231 cubic inches per gallon) = 1772.9 gallons
Eight (8.02083) cubic feet per 60 US gallons of water.
1 cubic foot is 7.48 US gallons
There are 7.481 gallons in one cubic foot.
