Volume
- In cubic feet
- 33 ft³
How this was calculated
- 1Calculate the volume in cubic feet10 × 10 × 0.33 = 33 ft³
- 2Divide by 27 for cubic yards÷ 27 = 1.222 yd³
Formula
Cubic yards = (length × width × height in ft) ÷ 27
One cubic yard is a 3-by-3-by-3-foot cube, or 27 cubic feet. You first calculate the volume in cubic feet by multiplying length, width and height, then divide by 27 to convert it to cubic yards.
Worked examples
A driveway 10 × 10 ft with a 4-inch (0.33 ft) thickness
→ About 1.22 cubic yards of concrete needed.
Common mistakes
