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).
In geometry, a triangular prism is a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides.A right triangular prism has rectangular sides, otherwise it is oblique..4.3.
