Question 1056578
This will use Pythagorean Theorem Formula in THREE dimensions, instead of just two dimensions.


You already know, h for hypotenuse and dimensions named x and y, {{{x^2+y^2=h^2}}}.  In your example, you have one additional dimension, which you can call whatever you want; maybe like, z.  You can then say, z is for height, and {{{x^2+y^2+z^2=h^2}}}.
