Easily determine the slant height (l) of a regular triangular pyramid using our free online calculator. Simply input the base side length and the pyramid height to get instant, accurate results. This tool is perfect for students, educators, and anyone working with 3D geometry problems.
Formula:
The slant height (l) of a regular triangular pyramid (where the base is an equilateral triangle and the apex is centered) is calculated using the following formula:
l = √(h2 + (s / (2√3))2)
- l = Slant Height
- h = Pyramid Height (perpendicular distance from the base centroid to the apex)
- s = Side Length of the Equilateral Base Triangle
