adius, r, of the base of the pyramid using the lateral edge length, e.
Using the lateral edge length, we can calculate the slant height of one of the triangular faces of the pyramid, which will be the hypotenuse of a right triangle with base edge length e and height h.
This right triangle can be represented by the Pythagorean theorem:
r^2 + h^2 = a^2
r^2 + h^2 = 24^2
r^2 + h^2 = 576
We also know that the lateral edge length, e, is equal to the base edge length of the pyramid times the square root of 2. Since the base of this pyramid is a square, the base edge length is equal to 1/4 of the perimeter. The perimeter P of the base would be equal to e * 4.
P = e * 4
P = 25 * 4
P = 100 in
Each side of the square base would be 100 / 4 = 25in. The radius r would be half this, i.e. 25/2 = 12.5in.
We can then find h by rearranging the Pythagorean theorem:
r^2 + h^2 = 576
(12.5)^2 + h^2 = 576
156.25 + h^2 = 576
h^2 = 576 - 156.25
h^2 = 419.75
h = sqrt(419.75)
h ≈ 20.49
Therefore, the height of the square pyramid is approximately 20 inches when rounded to the nearest whole number.
