Code to add this calci to your website

#### Formula:

c =((((n × t/12.0)×(n×r/12.0))/2)+((n×(t/12.0×r/12.0))/2))×w × 0.037037
**Where,**
c = Concrete Yardage
n = Number of stairs
t = Tread(inch)
r = Riser(inch)
w = Width(ft)
### Example:

Calculate the concrete yards for stairs with the number of stairs of 100, tread of 200 inches, riser of 300 inches, and width of 40 ft.

#### Solution:

Concrete yardage stairs = ((((100 * 200/12.0)*(100*300/12.0))/2)+((100*(200/12.0*300/12.0))/2))*40 × 0.037037

= 3117287.417 Cubic Yards
