Astandard interior staircase has steps each with a rise (height) of 19 cm and a run (horizontal depth) of 23 cm. research suggests that the stairs would be safer for descent if the run were, instead, 28 cm. for a particular staircase with a total height of 4.57 m, how much farther into the room would the staircase extend if this change in run were made? start by making a sketch.
