Step-by-step explanation:

The question should be :

A solid right pyramid has a square base with an edge length of s units and a height of h units.

The formula for the volume of the pyramid is given by :

A is area of base and h is height.

As edge length is s units.

A = (s)²

So,

So, the required volume is one-thirds s²h unit³.
