On a standard 6 Sided Cube, it would be 3, because each perpendicular face takes up two faces, so it would be 6 divided by the 2 different faces, equaling 3 different Perpendicular Faces.

Each lateral face is perpendicular to its lateral neighbours so that makes 4 pairs. In addition, opposite lateral faces may be perpendicular, making 6 pairs in all.
1 at the base
A triangular pyramid has four faces and 2 pairs.
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!
4, obviously.
A square-based prism, also known as a square prism or rectangular prism, has 4 pairs of perpendicular faces. Each of the four lateral rectangular faces is perpendicular to the two square bases. Additionally, the two square bases are also perpendicular to each of the lateral faces, but they are not counted as a pair since they are parallel to each other. Thus, the total number of distinct pairs of perpendicular faces is 4.
