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.
Learn more about ShapesA pentagonal pyramid has six different faces. A pentagonal pyramid consists of a base that is in the shape of a pentagon, with five triangular sides that meet at the apex.
Full Answer >A pentagonal pyramid is characterized by six faces, six vertices and 10 edges. This three-dimensional polyhedron is a type of pyramid containing five triangular lateral faces and one pentagonal face, which is the base of the pyramid.
Full Answer >A cylinder has zero vertices. A cylinder does not have a vertex because there is no point where two lines meet. This is because a cylinder, unlike a prism, has circular faces; there is no corner where two straight lines meet.
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.
