Measure the length, width, and thickness of the area in feet
Multiply length × width × thickness to get cubic feet
Divide cubic feet by 27 to convert to cubic yards
Use the formula: yards = (length × width × thickness) ÷ 27
For multiple sections, calculate each section separately and add the totals
Round up to the nearest quarter yard or full yard when ordering
Add extra for waste, spillage, and uneven ground
Convert inches to feet by dividing inches by 12 before calculating
