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).
There are eight vertices in a rectangular prism. Any prism is a three dimensional figure; it has two bases and is formed by rectangles connecting the edges of each base to each other. So in the case of a rectangular prism is a rectangle. Thus, the number of faces of any prism is the number of edges of the base + 2. Also, the number of vertices is just the number of vertices of the base shape, times two. A rectangular prism has eight vertices because the base (a rectangle) has four vertices. That times two is eight.
