A standard interior staircase has steps each with a rise (height) of 21 cm and a run (horizontal depth) of 27 cm. Research suggests that the stairs would be safer for descent if the run were, instead, 35 cm. For a particular staircase of total height 6.30 m, how much farther would the staircase extend into the room at the foot of the stairs if this change in run were made? Run Length Number i Units Rise
