133,680.6 cubic feet.
There are 748.1 US gallons of water in 100 cubic feet.
7.48 = one cubic foot
One US gallon = about 0.1337 cubic feet.
ten gallons is about one and a third cubic feet, so I would say that 30 gallons is about 4 cubic feet
748
Multiply the number of cubic feet in the tank by 7.5 to find gallons.
1 gallon = 231 cubic inches1,728 cubic inches = 1 cubic foot3 cubic feet = 5,184 cubic inches = 22.442 gallons. (rounded)
one cubic foot , a volumetric measure, when filled with a liquid [ including water] , will hold 7.48 gallons [also a volumetric measure] of any liquid, 6118 cubic feet x7.48 gallon/ft3 = 45,762.64 gallons Question- what is so special about 6118 cubic feet?
1 U.S. gallon is exactly 231 cubic inches. One cubic foot is 1,728 cubic inches. Thus, 2,398 gallons is 2398 x 231 ÷ 1728 = 320.566 cubic feet. (For comparison, one cubic meter is exactly 1,000 liters.)
One Imperial gallon is 0.1605 cubic feet.
That depends on the rate of flow. However, at any one moment, 2,700 cubic feet can contain a maximum of 20,197.4 US gallons of water.
