if that is 3 ft deep it would require 96 yards... IF it is 3 inches deep it would require 24 cubic yards
one ton equals one cubic meter of soil was 100mm deep it would cover 7sqm
That depends upon how deep the soil bed is and how much moisture is in the topsoil. But here are some ballpark numbers for you: A yard of soil will cover a 10' by 10' area to a depth of three inches. In other words, figure a third of a yard per 100 square feet for every inch of depth. Length x width x # of inches deep divided by 324 = the number of cubic yards needed for that task.
It takes 5.0926 cubic yards or 137.5 cubic feet.
That's 13 cubic yards of mulch for every 2 inches deep.
24 cubic feet.
15.833... [cubic] yards.
You already have a square yard of topsoil, so how does 20 inches of depth get you the volume of topsoil? There are 36 inches in a yard, and you have 20 inches of topsoil depth that's 20/36ths of a yard of topsoil depth. That's 0.555... or about 0.56 yards. The volume of topsoil is 1 yard by 1 yard by 0.56 yards, or about 0.56 cubic yards of topsoil.

62/3 cubic yards for every 1-foot deep. 5 cubic yards for every 9-inches deep. 31/3 cubic yards for every 6-inches deep. 5/9 cubic yard for every 1-inch deep.
That's 13 cubic yards of mulch for every 2 inches deep.
One cubic yard of mulch will cover approximately 160 square feet at 2" deep, so you would need approximately two cubic yards of mulch to cover 271 square feet at 2" deep.
