A regular pyramid is a right pyramid whose base is a regular polygon. There are only three regular pyramids: a regular tetrahedron, a regular square pyramid, and a regular pentagonal pyramid.
The volume of a regular pyramid is 1/3*area of the base*hight
Basically, the same as the volume of any other pyramid: the volume is (1/3) x base x height. The "base" refers to the area of the base; for instance, if the base is a regular pentagon, use the formula for a regular pentagon.
The apex.
A regular pyramid has a regular polygon base and a vertex over the center of the base. By:Cherrylvr :)

A regular pyramid has an equilateral triangle base, not just a regular polygon. It has an apex above the centre of the base.

A regular pyramid has an equilateral triangular base
A regular pyramid is a right pyramid whose base is a regular polygon. There are only three regular pyramids: a regular tetrahedron, a regular square pyramid, and a regular pentagonal pyramid.
Its vertical height is that of the perpendicular from the centre of the base to the apex; the slant height is the length of the sloping "corner" between two faces. The height of a regular pyramid is the vertical distance from the center of base to the top and is usually shown with a line perpendicular to the base, denoted with a right angle to the base. The slant height it the height of the lateral face (the triangles) from the edge of the base to the top of the pyramid. It is the height of the triangle, not the pyramid itself. The slant height will also be the hypotenuse of a right angle formed from the altitude of the pyramid and the distance from the center of the base to the edge.
