convert inches to gallons in a 400 gallon tank
Gallons in a rectangular tank =(tank's length in inches) times (tank's width in inches) times (water depth in inches) divided by (231)
The tank has a volume of 48 inches x 18 inches x 15 inches or 12960 in3. The average imperial gallon has a volume of 231 cubic inches. 12960 in3 ÷ 231 in3/US gallon = 56.10 gallons.
1 gallon = 231 cubic inches Volume of the tank is (10 x 20 x 12) = 2,400 cubic inches The tank has a capacity of (2,400 / 231) = 10.39 gallons (rounded), but we have no way of knowing how many gallons are "in it".

You actually have a 20 gallon tank. There are 231 cubic inches in a gallon. So if you take your length times your with you get: 24x12 = 288in square. Then multiply that times the 16 inches of height and you get 4,608 inches cubed. Divide that number by the 231 cubic inches per gallon and you get: 4608 (inches cubed)/ 231(cubic inches per gallon)=19.94 Gallons or a 20 gallon tank.
