How to Calculate Concrete Volume
Formula
Cubic Feet = Length (ft) x Width (ft) x Depth (ft)
Cubic Yards = Cubic Feet / 27
There are 27 cubic feet in one cubic yard (3 x 3 x 3). Always order 5-10% extra concrete to account for spillage, uneven ground, and slight over-excavation.
Example Calculation
A concrete pad 20 ft long, 10 ft wide, and 0.5 ft (6 inches) deep.
- 01Cubic feet = 20 × 10 × 0.5 = 100 cu ft
- 02Cubic yards = 100 / 27 = 3.70 cu yd
- 03Order approximately 4 cubic yards to allow for waste.
