It depends on the depth you wish to cover with. If it's going to be 1 foot deep, there are 27 cu ft in a cu yd so it will cover 27 cu ft at a depth of 1 foot. If you want 6" depth, you have 54 (27 times 2), 3" depth you will have coverage for 108 sq ft. I hope this gives you g good idea of what you are going to need.

To find the volume in cubic feet needed to cover 21,000 square feet, you would also need the height of the coverage area. The volume (cubic feet) is calculated by multiplying the area (square feet) by the height (feet). Without the height, it's not possible to determine the amount of cubic feet needed to cover 21,000 square feet.
