Measure the length, width, and thickness of the concrete area in feet
Multiply length by width by thickness to get cubic feet
Divide cubic feet by 27 to convert to cubic yards
Use the formula: yards = (length × width × thickness) ÷ 27
Convert inches to feet before calculating if thickness is given in inches
Round up to the nearest tenth or whole yard as needed for ordering concrete
Add extra concrete for waste, spillage, and uneven ground
Verify all measurements before placing the order
