math formula for building stairs. The total run the number of runs treads times the tread length. If there are no limitations for total run use the formula 2 risers 1 run 23 to 24.
In elementary algebra the quadratic formula is a formula that provides the solutions to a quadratic equation. Using a target run of 10 inches the riserun ratio is well within the safe and comfortable formula for this stair. You can use any number you want but I will use 7 for this example because that is my Target Step Height.
Like take 093 from the first tread 0875 from the 2nd and so on.
Treads may be cut to suit other widths. Determine how you will attach the stairs to the existing structure. In elementary algebra the quadratic formula is a formula that provides the solutions to a quadratic equation. It is equal to the number of treads multiplied by the typical Tread Depth B.
