Enter the center height and the length of the side of the pyramid to calculate the slant height.
Slant Height Formla
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
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.
