|Spanning horizontally is nothing but considering the design as a horizontal slab. Waist slab is the minimum distance of the stair upper surface to the lower slab bottom. That can be decided by the design. But for an RCC minimum slab width must be greater than 3.5 inches so we can say 80 mm.|

|Minimum width of stair 90 cm.
so minimum width of the waist will be 90cm.
Right answer 90 cm.
