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.
to what depth???
The circle is the soil in the world, and the square is a tree coming out of the soil.

The answer depends on where the soil is, and also on how deep you dig into the square metre area.
It depends on plants, soil, and weather. But 8 square meters is one answer.
growing commercially? 6 qubic meters per 1000 sqm

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.
None of them. Nothing eats stone. Many kinds of ants can burrow through soil that is very hard.
Soil is crushed stone from thousands of years ago.
soil character are mud, sand and stone :p
