The concrete yard is a necessary thing that needs to be calculated in order to determine the concrete volume of the material. It will assist you to determine the space occupied where the concrete would be spilled. The section of this page shows you online concrete yards calculator to calculate the concrete yardage stairs by multiplying the number of stairs, tread, riser, width and 0.037037. This yardage calculator for stairs fetches output in cubic yards units.

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
