2.37 cubic yards of stone for every 3 inches deep it needs to be
The 4 inches is 4/12 of a foot or 1/3 foot. Length times width times height is the volume, so 2856 (the area in square feet) times 1/3 (the depth in feet) = 952 cubic feet.
Any reason why it shouldn't be 220, apart from the shape of the area?
To determine how many 6-foot by 3-foot plasterboard sheets are needed for a 6.5 square foot area, first calculate the area of one sheet. Each sheet has an area of 18 square feet (6 feet x 3 feet). Dividing the total area needed (6.5 square feet) by the area of one sheet (18 square feet) gives approximately 0.36 sheets. Since you can't purchase a fraction of a sheet, you would need at least 1 sheet to cover the area.
To cover a 30x30 area, which has an area of 900 square feet, you would need to determine the area of one 12x12 stepping stone, which is 1 square foot (12 inches x 12 inches = 144 square inches, or 1 square foot). Therefore, you would need 900 stepping stones to cover the entire 30x30 area.
A 12x12 tile covers 1 square foot (since 12 inches = 1 foot). To cover a 144 square foot area, you would need 144 tiles, as each tile covers 1 square foot. Therefore, you need a total of 144 tiles to completely cover the area.
You will need 1500 cubic feet.
Take the sq foot and divide by 140 if you want the stone apx. 2" deep.
To cover an area of 1 square foot with 1/2 inch of water, you would need 0.623 gallons of water.
The 4 inches is 4/12 of a foot or 1/3 foot. Length times width times height is the volume, so 2856 (the area in square feet) times 1/3 (the depth in feet) = 952 cubic feet.

A square foot will cover a square foot, regardless of the depth of the material the cover is made of.

It should take about 825 1 foot square tiles to cover a floor with those dimensions. This assumes roughly a 10% waste factor.
