How do I calculate cubic yards?
Multiply length × width × depth in feet to get cubic feet, then divide by 27 to get cubic yards.
When you need cubic yards
Bulk materials — concrete, soil, mulch, gravel, and sand — are sold by the cubic yard. Calculating volume up front tells you how many deliveries you need and prevents paying for material you can't use before it degrades.
The conversion
There are 27 cubic feet in a cubic yard. Measure length and width in feet and depth in inches, multiply for cubic feet, then divide by 27. For coverage: one cubic yard covers about 100 sq ft at 3 inches deep, or 300 sq ft at 1 inch.
