How to calculate volume of concrete in staircase

Step-1:- Calculate the number of steps in Stair
Number of Stair = H/R , H =height of stair, R=rise of Stair
Step-2:- Then calculate Horizontal length of stair
Horizontal length of stair= Tread X Number of steps.
Steps-3:- Now Calculate waist length
using Pythagoras theorem and calculate waist length
Step-4:- First of all Calculate Waist volume = BxLxD
Step-5:-then Calculate steps volume = area of step X B
