2.5 cubic feet of water weighs about: 156 pounds.
The weight of any volume of water will depend on the gravitational force acting upon it. 57 cubic feet of water would weigh nothing in a spaceship, for example.
Roughly 72 pounds.
The weight of 0.4 cubic feet depends on the density of the material. To convert volume to weight, you need to know the specific density. If we assume an average material density of 100 lbs/cubic foot, then 0.4 cubic feet would weigh 40 lbs.
Depends on the size of the aquarium. Water weights 10 pounds per gallon.
If the weight is 62.5, then it weighs 62.5

On average, 8 cubic feet of concrete can weigh around 4,000-4,500 pounds, depending on the density of the concrete mix.
100 cubic feet = 2831.7 litres.
2.3 million cubic feet of water is approximately 17.2 million gallons.
