How much does a 55 gallon fish tank filled weigh?

Answer 1

1 US Gallon of water weighs 8.35 lbs. The tank will not be filled to the brim so you can deduct about 0.5 gallons from its maximum capacity. So the weight of the water would be 8.35lbs x 4.50 which is 37.5lbs. You would also have to weigh the tank and other things like lights, cover glass, heater/thermostat, thermometer, filter complete with media, and gravel etc. Everything that you use in the tank must be weighed and added to the water weight to obtain an accurate total weight.

Answer 2

A 2 by 5 foot fish tank would weigh nothing, because it would be a 2 divisional object, which have no mass. A third measurement, such as the height, would be needed to provide us with a three dimensional object on which we could calculate the mass.

Answer 3

Depends on what material the tank is made of, glass, plexi-glass, wood? What are the thickness of these materials?

Answer 4

A gallon weighs 8.345404 lb. X 10 = 83.5 lb. + the aquarium.

Answer 5

About 478 lb.
