A staircase room of dimensions 5.2 m × 2 m for a building is shown in Figure, connects the Ground floor with the first floor. The Ground floor level is +0.0 m and the first floor level is +3.0 m. The steps have to provided with a rise = 15 cm and tread = 30 cm, with equal number of steps in both flights, and a landing of 1.2 m width in between the flights. What is the distance X at the Ground floor marked in Figure for the staircase room?
