Formula for Concrete Slab Volume:
The volume of a rectangular concrete slab is calculated by multiplying its length, width, and thickness. To get the result in cubic yards (the standard unit for concrete orders), the total cubic feet are divided by 27 (since 1 cubic yard = 27 cubic feet).
Volume (Cubic Yards) = (Length × Width × Thickness) / 27
- Length: Total length of the slab (in feet).
- Width: Total width of the slab (in feet).
- Thickness: Total thickness of the slab (in feet).
- 27: Conversion factor from cubic feet to cubic yards.
Note: Ensure all dimensions are converted to feet before performing the multiplication. Our calculator handles this conversion automatically from your feet/inches input.
