Doing the math gives 53 gallons; however its probably a standard 55 gallon aquarium.
Filled to the brim it will hold 59.04 US gallons. When in use as a fish tank it will have considerably less than that because a tank is never filled to the brim. I would stock it as a 50 gallon tank when in use. The basic rules of fish keeping state :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank need at least 50% of its water changed every week.. Follow those rules and your fish stand a chance of survival. Fail to follow those rules and I can guarantee failure.
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.
This depends on density of the contents of the tank. For example, if it were to be water the tank would measure 1x1x1 meter. However, if you were talking about feathers...... water is in the tank
That depends on the weight of the fish as compared to the weight of the water their bodies displace. If it's a heavy, dense fish, then the tank with the fish would weigh more. If it's a light, less dense fish, then the tank with water only would weigh more. This assumes that the water displaced has been removed from the tank, right? If you are adding the fish to the water then I think it should increase the weight regardless of the density of your fish. The question then might be, does the fish weigh less when it is swimming than it would on a dry scale?
Personally, I think fresh water is easier because a salt water tank means that you need to purchase aquarium salt, and you need to add it to every water change. I have never raised a saltwater aquarium, but I believe you also have to measure the amount of salt the fish need. So if you're a first-timer, go for the fresh water tank. But the good thing about saltwater tanks is that it is more diverse and colorful.

A 60x20x20-inch fish tank holds 104 gallons.
Approximately 43 gallons
It depends on the fish tank. They range from less than 2 gallons to over 300 gallons.
34.6 Gallons (131 Litres) :)
Answer: 11.1 x+2.4=13.5 13.5-2.4=11.1
As a very rough estimate, I would suggest 40 gallons!
5 foot fish tank holds 566.3 liters. By:Radhika
About 29 gallons
It holds 160 quarts.
This size tank can hold up to 7,779.74 US gallons of water.
its fake!!!!!!!!!!!!!!!!
