It is: 125*47*95 = 558125 cubic inches
A tank measuring 62 inches by 46 inches by 44 inches has a volume of 125488 cubic inches, which is 10457.3 cubic feet. That equals 78,226.286 in US gallons It equals 65,137.007 in Imperial gallons
22x20x13= 5720 cu inches assuming you want in gallons it is 24.76 gallons
you multiply it together so it is 28,080(your measurement here)^3
Assuming we are talking about a common rectangular aquarium. (Length of tank in inches) x (Width of tank in inches) x (Depth of tank in inches) = Volume of the tank in cubic inches Volume/231 = Gallons in tank Please keep in mind that rocks, plants, fish, and decorations reduce the volume of the tank somewhat.

To calculate the tank's volume, you would have to multiply its dimensions together. In this case, it will be 18 x 12 x 30, which is 6480 units cubed
Assuming it is a rectangle, 56.232 imperial gallons
There would be no gallons in a 36 by 360 inch tank. It will require a third measurement to have volume.
20"x16"x12"=3840 cubic inches. 1 gal of water has a volume of 231 cubic inches therefore the nominal/quoted/rated volume of water the tank will hold is 3840 divided by 231 which is just over 16.6 gallons of water. The tank will never hold that amount of water when keeping fish. At least 1 inch will be left empty at the top and if the tank is set up with plants lights etc an average of 2 inches will be taken up with gravel at the bottom. So 3 inches is a quarter of 12 (which is the depth of the tank) that is reducing the holding capacity of the tank by one quarter so 16.6 divided by 4 will give how much less water the tank will actually hold. That amount is 4.15 gallons. So the tank will actually hold 16.60 minus 4.15 gallons. Which leaves you with 12.45 gallons if it is a planted tank. Applying the basic rule of fishkeeping "1" of fish needs a minimum of 1 gallon of water, you will see that your tank can house a maximum of 12.5 inches of fish.
