A heptagonal what? Prism, pyramid or something else?
There is no such shape as a perpendicular prism.
Heptagonal Prism
It has 9 faces It has 21 edges Its end faces are parallel to each other
A heptagonal prism gas 21 edges.
An heptagonal based prism, also known as a heptagonal prism, has two faces that are perpendicular to each other. These faces are the bases of the prism, which are heptagons in this case. The perpendicular edges are the edges that connect the vertices of the bases at right angles, resulting in a total of 14 perpendicular edges in a heptagonal prism.

Well, honey, an heptagonal prism has 7 faces, and each face has 2 pairs of parallel edges. So, if you do the math, that's a total of 14 pairs of parallel edges in an heptagonal prism. Math doesn't have to be boring, darlin', it can be sassy too!

There are 7 or 9, depending on the bases.
It doesnt matter -.- GET A LIFE !
Assuming a regular decagon is the base of the prism, it would be 10 faces. With an irregular decagon, it is possible that two (or more) of the edges of the decagons are perpendicular, so all 12 faces could have perpendicular edges.
