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)

1 cubic yard of rock = 27 cubic feet of rock. 27 cubic feet of rock @ 6" (1/2 of foot) = 27/(1/2) = 54 sf
Snow is not uniform for density so you would have to weigh the cubic foot you are interested in. Each pound or kilogram would be composed of 1/9 hydrogen and 8/9 oxygen (by mass) since the molecular weight of water is 18, the atomic weight of hydrogen is 1 and the atomic weight of oxygen is 16. Based on 1 cubic foot of snow being about 10% the weight of a cubic foot of water, it would weigh approximately 6.25 pounds and contain about 5.56 pounds of oxygen.
On one site I found the weight of one cubic yard of topsoil listed as 1,35 US tons
More info needed. How much does 0.4 cubic feet of what weigh? Air? Lead? Water? Dirt?
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.

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.
The weight of 2.25 cubic feet of water is approx 4495 pounds-force (lbf).
To figure out consider this: a dumpster that can enclose 30 cubic yards would have the dimensions approximately of :6feet tall, 22 feet by length and 8 feet wide
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.
