How many perpendicular faces does a octahedron have?

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The number of perpendicular faces will depend on which particular octahedron you have in mind. The heptagon-based pyramid, for example, has none.


How many parallel faces does an octahedron have?

There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.

How many perpendicular faces does a pentagonal prism have?

A pentagonal prism has only 7 faces. Each of the five lateral faces is perpendicular to the two bases: that makes 10 pairs of mutually perpendicular faces. In general, the lateral faces are not perpendicular, but four of them may be perpendicular to one or more of its neighbors - at most 4 more pairs. Still not 25!
