In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons) is a polyhedron composed of four triangular faces, three of which meet at each corner or vertex. It has six edges and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces. The tetrahedron is the three-dimensional case of the more general concept of a Euclidean simplex.
The name of the prism tells us how many lateral sides there are -- triangular -3 lateral sides or faces . Since it is a prism, that tells us how many bases there are 2 . So the total number of faces is 5. There is also a formula that connects these 3 descriptors in any 3 d shape.
