Polygons have the same number of vertexes/vertices as the sides. So, A 20 sided polygon will have 20 vertexes/vertices.
A square is not a polyhedron, it is a polygon. A cube is not a polygon, it is a polyhedron.A square has 4 edges and 4 vertexes. It has no faces because it is not a polyhedron. If you cut the corners off of a square, the new polygon has 8 edges and 8 vertexes.A cube has 6 faces, 12 edges, and 8 vertexes. If you cut the corners off of a cube, the new polyhedron has 14 faces, 36 edges, and 24 vertexes.
A quadrilateral is a polygon with four sides and four vertices.
A cylinder has no vertices (not vertexes!) It has 2 circular edges.
6 edges 4 vertexes

Decagon
22 because usually the number of sides is the number of vertexes and vice versa.

8 vertexes
Not sure about vertexes or prisim. A rectangular prism, on the other hand, has 8 vertices. Not vertexes.
A cylinder has no vertices (not vertexes!) It has 2 circular edges.
6 edges 4 vertexes
