If I have 14 stairs that go up 9 feet, how high should each step be if they are equal?

Answer 1

In an ideal mathematical world, each step should be 7.714... inches in height.

9 feet is indeed 108 inches, but 108/14 " = 7.714... ".

(98/14, not 108/14, equals 7; 108/14 = 54/7 = 7 5/7.)

Note that if you make each step just 7.7", 14 of them will give you 107.8", short by just 0.2". The extra 0.2" is hardly noticeable, and could be given to the bottom step, for example.

However, carpenters generally work in fractions like1/8th, 1/16th, or 1/32 " of an inch. If you make even steps of 7 11/16 ", you'd have to absorb an extra 3/8 " somewhere; if you used 7 3/4 ", you'd have 1/2 " too much and would probably want to reduce the top and bottom steps by 1/4."

The best choice to make with typical carpenters in mind would be 7 23/32 "; you'd then have just 1/16 " (2/32 ") too much from 14 such steps. You could easily reduce the top step, say by that much without it really being noticed.

Live long and prosper.

Answer 2

9 feet is equal to 108 inches. 14 stairs are there and thus each step is equal to 7 inches.

Answer 3

Given: height = 9 feet, stairs = 14

9 / 14 = 0.642857142 feet each
(or 0.642857142 feet x 12 = 7.714285714 inches each)

check:
7.714285714 inches x 14 steps = 108 inches / 12in/ft = 9 feet

Answer 4

I assume you mean 14 steps instead of stairs, so follow this.
Multiply the 9 ft. by 12 in, which =108 in. divide 108 by the 14 steps = 7.7142857
simple math, try it.

Answer 5

= 9 / 14

Answer: 9/14 foot or 7 5/7 inches

A foot is equal to 12 inches.

Answer 6

(9 feet *12 inches/foot)/14

or 108 inches /14 steps = 7.71 inches/step.

Answer 7

Perhaps he'll max out at 5'3" or around there Your average 14 y/o boy is around 5'3" - 5'5". Your average man is around 5'10".

Answer 8
