A prism has edges that correspond to the number of edges in its base shape. For example, a triangular prism, which has a triangular base, has 6 edges (3 from the top triangle and 3 from the bottom triangle). In general, a prism with an n-sided polygon as its base will have a total of 3n edges: n edges from the top base, n edges from the bottom base, and n vertical edges connecting the two bases.
A triangular prism has 9 edges!
A Pentagonal Prism has 15 edges.
The rectangular prism has 12 edges.
A square prism has 12 edges.
A triangular prism has 6 edges and so an octagonal prism will have 16 edges.
A triangular prism has 9 edges!
There are 30 edges on a decagonal prism.
A heptagonal prism has 20 edges.
A rectangular Prism has 12 edges.
A square prism has 12 edges.
A Pentagonal Prism has 15 edges.
The rectangular prism has 12 edges.
A triangular prism has 6 edges and so an octagonal prism will have 16 edges.
A hexagonal prism has 18 edges.
There is no such shape. A tetrahedron has 6 edges, but it is NOT a prism.
There are twelve edges in a rectangular prism.
A triangular prism has 9 edges.
