Start with an octahedron in the form of a quadrilateral based dipyramid a regular octahedron is a special case of this). This shape has six vertices - chop these off so as to remove a quadrilateral based pyramid. You will be left with a truncated octahedron. It is an octahedron which has been truncated (shortened) by cutting off its extremities.
It can be but need not be. A heptagon-based pyramid is an octahedron. However, the term is often used for the Platonic solid bounded by eight equilateral triangles - in the form of two square based pyramids stuck together base-to-base.

No, it is not.
Not necessarily. A heptagon-based pyramid is an octahedron and it has no parallel faces.
To find the perpendicular height of a square pyramid, first compute for the volume of the pyramid. Then divide the volume by the area of the base to find pyramid's height.
Volume XIII of Elements deals with the construction of the five regular Platonic solids (pyramid, cube, octahedron, dodecahedron, icosahedron) inside a given sphere.

The formula to find the volume of a triangular pyramid is: 1/3 (1/2 B H ) H
Well I think that it do not have that much volume.

Here are three; cube, octahedron, hexagonal pyramid.
