We need to know the height and the length of a side.

The slant height is given by

√[(1/4)s^2 + h^2] where s is the side length and h is the height

Alternatively...if we know the height and the angle - θ - that the side of the pyramid makes with the base along one edge [ * not at a vertex, though!!!* ], we can use

slant height = height / sin θ
