That depends on how thin you spread it. If it's a meter thick, it only covers one square meter. If it's a centimeter thick, it covers a hundred square meters.
30 metres square = 900 square metres 6 inches = 0.1524 metres. So amount of soil required = 900*0.1524 = 137.16 cubic metres
None, since a square is a two dimensional shape.

The answer depends on where the soil is, and also on how deep you dig into the square metre area.
150
It depends on plants, soil, and weather. But 8 square meters is one answer.
growing commercially? 6 qubic meters per 1000 sqm
None, since a square is a two dimensional shape.
None of them. Nothing eats stone. Many kinds of ants can burrow through soil that is very hard.
there is Zero cubic meters of soil in the hole, after all if there was any soil in the hol eit wouldn't be hole, now would it?? To answer your question, you must also know the length of the hole, them multiply all of the measurements together to find the cubic space of the hole.
The unit rate for soil would typically be measured in kilograms per square meter. This unit rate indicates how many kilograms of soil are present in each square meter of the specified area.
It depends on the density of the top soil. On average, 1 ton of top soil is approximately equal to 0.7647 cubic meters, which is equivalent to 764.7 liters.
