It's not clear whether the 6 in the question is 6 inches or 6 feet.
If it's 6 inches: (20 x 20 x 1/2 foot) = 200 cubic feet = 7.41 cubic yards
If it's 6 feet: (20 x 20 x 6) = 2,400 cubic feet = 88.9 cubic yards
(43,560) x (depth of the topsoil in feet) cubic feet
one ton equals one cubic meter of soil was 100mm deep it would cover 7sqm
it depends how thickly you lay it.
The cost of a centimeter of topsoil can vary depending on factors such as location, quality, and supplier. On average, prices can range from $0.50 to $3 per square foot. However, it's important to contact local suppliers for accurate pricing information in your specific area.

Deforestation can affect topsoil in two significant ways. First leaves and branches that fall from trees as well as fallen trees themselves decompose. This decomposed matter is a major component of topsoil. If an area is deforested then much less new topsoil will be formed. Secondly, when an area is deforested wind and rain can cause the unprotected topsoil to be blown or washed away.
This will depend on what is under the topsoil.
You need to specify how thick you want the top soil to be

Depends if you want fill dirt or topsoil, I have gotten fill for $40 a load but it had alot of rock. I bought large dump loads today for $100 a load and he will spread it out but it just depends what they have and how far they have to haul it.
This question has no real answer as it depends where you stay and the availability of top soil. How much is a cubic yard of topsoil in Iceland? How much is a cubic yard of topsoil in the Sahara Desert? How much is a cubic yard of topsoil in Washington DC? etc. etc. Check a local newspaper or nursery/ garden centre
I asked the same question! The steeper one will of course loose it's topsoil. Because the soil at the top of the hill can't stay up at steep hill, eventually gravity will pull it down to a reasonably flat ground. A sloping area topsoil will not fall because it can easily grip on the ground without gravity pulling at it that much. I hopes this helps you!
The answer will depend on the depth to which the dirt is spread.

There is no guarantee that it will ever recover. The layer of topsoil in a rainforest is extremely thin. Because there is so much competition for food in the forest, little material builds up to form topsoil. When the trees are cut down and the thin layer of topsoil is exposed to sun, wind, and water, it is more susceptible to erosion. When the topsoil disappears, the land becomes un-arable, and becomes essentially desert.
