2.5 cubic feet of water weighs about: 156 pounds.
10pounds
On average, 8 cubic feet of concrete can weigh around 4,000-4,500 pounds, depending on the density of the concrete mix.
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.
The weight of 2.25 cubic feet of water is approx 4495 pounds-force (lbf).
It depends on the density of the substance
Wood has a wide range of densities.
Roughly 72 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.
Around one hundred pounds.
Wheat and soybeans: 1 bushel = 60 lb = 27.2155422 kg
A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.
