Multiply 36*12*16 = 6,912 cubic inches
12*12*12 = 1729 cubic inches per cubic feet
6912 cubic inches/1729 cubic inches per cubic feet - 4 cubic feet
4 cubic feet * 7.48051948 gallons per cubic foot = 29.90 gallons
7.48051948 Gallons per cubic foot
Probably 25-30 gallons, be we cannot say for sure, since you did not say how TALL it is.
15 Gallons of water can fit into the tank.
A bit less than 75 US gallons.
Its a long explanation how but it should be about 25 gallons
A U.S. gallon is exactly 231 cubic inches. 60 x 18.75 x 19 = 21,375.0 cubic inches = 92.532 U.S. gallons
18.04
Making the assumptions that these measurements are in inches, and that the fish tank is a perfect cuboid, the volume of the fish tank is 49 x 19 x 21 = 19,511 cubic inches.Rounded to two decimal places, this is equal to 70.47 gallons.
A tank of 21 inches wide, 8 inches deep and 59 inches long will hold 36 gallons of gas. These gallons refers to US gallons.
231 cubic inches = 1 gallonVolume = (length) x (width) x (depth) = (48 x 19 x 11) = 10,032 cubic inches = 43.429 gallons
168.311 US gallons.
Any container 30 inches long 13 inches wide and 13 inches high has a volume of 22 gallons
= 93.09 gallons (US) = 77.51 gallons (imperial)
Assuming it is a rectangle, 56.232 imperial gallons
Approximately 201 gallons.
