Landscape supplies are sold by the cubic yard, but most people know their area in square feet. Add a depth and the conversion is simple: square feet × depth in inches ÷ 324.
How to convert square feet to cubic yards
Multiply the area (sq ft) by the depth in feet to get cubic feet, then divide by 27. With depth in inches, that is the same as square feet × inches ÷ 324, because 12 × 27 = 324.
