If the total rise is 57" for a set of stairs the largest possible unit rise is 7 1/8".

Quizplus · Accepted Answer

To find the largest possible unit rise, we can use the formula:

unit rise = total rise / number of steps

If we want the largest unit rise, we want to have the fewest number of steps possible. To find the minimum number of steps, we can divide the total rise by the maximum unit rise:

minimum number of steps = total rise / maximum unit rise

minimum number of steps = 57 / 7.125

minimum number of steps ≈ 8

Since the number of steps must be a whole number, we can round up to 9. Now we can use the formula for unit rise to find the largest possible value:

unit rise = total rise / number of steps

unit rise = 57 / 9

unit rise ≈ 6.33

This value is less than the given maximum unit rise of 7 1/8", so we can conclude that the statement is true.
