Sample Calculation 1
Two floors are 2700mm apart. Calculate the rise and going of a staircase from the lower floor to the upper floor that meets all building regulations.

Sample Calculation 2
Two floors are 2035mm apart. A stairs is to be constructed between the floors with a maximum overall going of 3300mm. Calculate a rise and going that will satisfy all building regulations and allow safe passage between the floors.
