Q: A: ### Quick Answer

**A triangular prism has six vertices.** In order to calculate the number of vertices on any type of prism, take the number of corners on one side and multiply by two. For example, a rectangular prism has eight vertices, or two sets of four.

Some other characteristics of a triangular prism are that they have five faces and nine edges. For comparison, a rectangular prism has six faces and 12 edges. Mathematicians have derived Euler's formula for these and similar shapes. It states that for a polyhedron the number of faces plus the number of vertices minus the number of edges is always two. For a triangular prism, this formula holds true: (5 + 6 - 9 = 2).
