Slant Height Formula
The following formula is used to calculate a slant height.
L = SQRT ( H^2 + (S/2)^2)
- Where L is the slant height
- S is the length of any side (Use the diameter at the base for a cone.)
- H is the height from the center to the top of the pyramid’
To calculate a slant height, square the length of the height from the center to the top of the pyramid, add it to the length of an side divided by 2 squared, then take the square root of the result.
Slant Height Definition
The slant height is defined as the total length from the center of a side, traveling along the surface of a side, to the top of the pyramid or cone.

FAQ
A slant height is a measure of the distance from the top of a pyramid or cone to the center of the side or a point along the base for the cone.
