You are designing a staircase to reach a second floor that is 113" above the ground floor of a building. The owner of the building wants you to make a staircase as close as possible to a 7.25" rise to meet their specifications

Step-by-step explanation:

total height, H = 113 inches

height of each stair case, h = 7.25 inches

Number of stair case, n = total height / height of each stair case

n = 113 / 7.25 = 15.6

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
