Concrete Volume Formula for Stairs
- $$n$$ β number of steps
- $$t$$ β tread length (inches)
- $$r$$ β riser height (inches)
- $$w$$ β width (inches)
- $$0.037037$$ β conversion factor to cubic yards
This formula combines the area of triangular and rectangular components of the steps, converting all dimensions from inches to feet before applying the conversion to cubic yards. Itβs commonly used in residential and commercial stair construction to accurately determine how much concrete is needed, avoiding under- or overestimation.
