How do you find the slant height to a square base pyramid?

To find the slant height of a square base pyramid, you can use the Pythagorean theorem. First, determine the height (h) of the pyramid and half the length of a side of the square base (s/2). The slant height (l) can then be calculated using the formula ( l = \sqrt{h^2 + (s/2)^2} ), where ( s ) is the length of one side of the square base. This gives you the length of the slant height from the apex of the pyramid to the midpoint of a side of the base.
