First of all covert height in cm so,

3.2*100 = 320 after that one riser is 13 cm.

320/13 = 24.6.

What is the exact formula? anyone please explain me.

Height of one flight = 320/2=160 cm.

No of rises in one flight=160/13=app. 13,so no of threads in one flight=13-1=12, so total no of tread in one storey =12*2=24.

3.20/0.13 = 25 (Height of a building/ riser).
For each storey, No of threads = 25 - No of storeys (Here it is 1).
i.e 25-1 = 24.

If it is a 2-storey building, then No of threads equal to 25-2 = 23 and Vice versa.
