A pentagonal prism has 10 vertices because there are two five-sided shapes at both ends of a prism. A pentagonal prism has 15 edges and seven faces. Five faces are between the pentagons on each end.
Know MoreComparatively, a rectangular prism has eight vertices, 12 edges and six faces. A triangular prism contains six vertices, nine edges and five faces. A hexagonal prism has 12 vertices, 18 edges and eight faces. Every time an edge of a regular polygon is added to a three-dimensional prism, the vertices increase by two, the edges increase by three and the faces increase by one. The reverse is true when an edge is subtracted from a regular polygon in a prism-like figure.

Full Answer >A trapezoid has four sides and four vertices. A vertex is a corner of a polygon. According to Reference.com, a trapezoid is a quadrilateral plane figure that has two parallel sides and two non-parallel sides.
Full Answer >A pentagon has five vertices. In geometry, a vertex is the point of meeting of two or more straight lines. The term "vertex" comes from Latin and has the plural "vertices."
Full Answer >A cube has a total of eight vertices, despite having six square faces that would all have four vertices of their own if pulled apart. A cube has six square faces that are joined not only at the sides, but at the vertices, essentially resulting in two squares that are joined by four lines, one at each corner.
