It all depends on the weight of the soil and what type of soil it is to find how much two feet of soil weighs.
1 cubic yard is 27 cubic feet, so 3 cubic yards is 81 cubic feet. At 125 lb per cubic foot, that much topsoil would weigh 10,125 lb. At 2000 lb per ton, that converts to 5.0625 tons (if we assume complete precision of all the numbers - if not, then we would be limited to 1 digit of precision because the 3 in 3 cubic yards is only precise to 1 digit. In that case we would have to round the answer off to be 5 tons)
On average, 1 cubic foot of topsoil can weigh around 75-100 pounds, so 75 cubic feet of topsoil would weigh approximately 5,625-7,500 pounds. The weight can vary based on moisture content and composition of the soil.
A 5-gallon bucket typically holds about 0.67 cubic feet of material. Crusher run gravel weighs approximately 2,500 pounds per cubic yard. Therefore, a 5-gallon bucket of crusher run gravel would weigh around 1,667 pounds.
For a raised bed that is 6 feet long, 3 feet wide, and 1.5 feet deep, you would need about 13.5 cubic feet of soil. This can be calculated by multiplying the length, width, and depth dimensions together (6 x 3 x 1.5 = 27 cubic feet) and then dividing by 2 to account for settling.
You will need about 3.7 cubic yards (around 4.75 tons) of gravel.
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 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.
2.5 cubic feet of water weighs about: 156 pounds.
10pounds
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.
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 2.25 cubic feet of water is approx 4495 pounds-force (lbf).
It would weigh 1,342 pounds.
It depends on the density of the substance
Wood has a wide range of densities.
Roughly 72 pounds.
One cubic centimeter of water would fit into that cup, and it would weigh 1 gram.
