Volume = area x height
3in = 3/12 = 0.25ft
volume_of_soil = 400sq ft x 0.25ft
= 100cu ft.

The language used in this question indicates some confusion, so we must clarify some points first.First, although a yard is a unit of length, when you go to a commercial garden center, a "yard" of soil is really a cubic yard. In other words, it's a volume; it has length, width, and height (or depth). But people in the business just call it a yard.Second, a square foot is a unit of area, not volume, so you cannot convert from cubic yards to square feet. However, a cubic yard of soil will cover a certain area of ground, but you have to know how deep you want the soil to be.If you're covering the ground to do a reseeding of lawn, it doesn't have to be too deep, so a (cubic) yard will cover a good amount of ground, but if you're filling in some flower beds or vegetable garden, it won't cover as much area.A cubic yard of soil will cover approximately an 18' x 18' square (324 square feet) to a depth of one inch.
very deep
a cubic meter of soil will weight 550-900 kg depending on its composition
i would take about 54 40 pound bags to make a cubic yard each 40 pound bag is about 1/2 a cubic foot and there are 27 cubic feet per cubic yard.
3,495.6 cubic yards.
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.
200 cubic feet.
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.
