Your calculations are intended first to provide which of these crucial pieces of information?
the number of stairs
You must determine how many stairs you will be building, because that will determine many of the other measurements for the project.
the height of each stair
the width of the handrail

Which of these terms refers to the vertical section of a step?
the rise
The vertical section of a step is known as the rise. The total rise of a stair case is how much vertical climb the stairs allow.
the base
the run

What is considered the ideal height for a single rise?
3 inches
7 inches
Research has shown that the ideal height for a step in 7 inches (18cm). You can only vary from that number by about an inch before the stairs are perceived as uncomfortable to climb.
12 inches

To determine how many stairs you will need, you should use which of these calculations?
Divide the total rise of the staircase by 7, and round to the nearest integer.
You must measure the total rise of the stairs, and then divide that into 7-inch units. You can then round to the nearest whole number to determine how many stairs you must build.
Calculate the slope of the stairs, divide that angle into 7-inch units, and add one.
Determine the square of the hypotenuse of the triangle produced by the staircase, and cut that into 7-inch sections.

Having determined the number of steps you need, how do you determine how high each rise will actually be?
Divide the total rise by the number of stairs you've calculated you need.
Even though the ideal height of a rise is 7 inches, you will not always have that option. You must account for the actual height of the total rise, and divide that by the number of stairs you need.
Multiply the number of stairs you need by 7 inches.
Add up the total number of stairs you need and divide that into 7-inch units.

The term run refers to which of these sections of a stair's step?

When calculating the rise of a step, you should round off to which of these?
the nearest quarter of an inch
Although accuracy is important, you can afford to round off to the nearest quarter of an inch (0.6cm).
the nearest half of an inch
the nearest inch

A staircase that has a total rise of 3 feet (91cm) will need how many stairs?
3
5
There are 36 inches in 3 feet. Divide 36 inches by 7 to get 5.14. Round that to the nearest integer, and you've calculated the total number of stairs you need.
7

The five steps of a 36-inch (91cm) staircase will each have a rise that is how high?
7 inches
7.25 inches
Divide 36 inches by 5 to get 7.2 inches. Round that to the nearest quarter of an inch, and the rise of each stair will be 7.25 inches.
7.5 inches

One way to save time on your project is to buy which of these?
pre-cut stringers
A stringer is the staircase's frame, on which the individual stairs will rest. You can buy pre-cut stringers at many hardware stores.
