How to find the number of side edges, base edges and side faces of a straight prism with 22 vertices?

Any prism has exactly two bases, and all the vertices of the prism belong to one of these bases, therefore, to determine how many corners at the base, you need to divide the number of prism vertices by 2:
22/2 = 11.
This means that the bases of the prism are eledecagons, therefore, there are exactly 11 side edges, side faces and base edges of this prism.
Answer: The prism has 11 side edges, 11 side edges and 11 base edges.
