Tetrahedron - Wikipedia
In geometry, a tetrahedron (pl.: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra. [1]

The volume of a tetrahedron is defined as the total space occupied by it in a three-dimensional plane. The formula to calculate the tetrahedron volume is given as, The volume of regular tetrahedron = (1/3) × area of the base × height = (1/3) × (√3)/4 × a 2 × (√2)/(√3) a = (√2/12) a 3 where 'a' is the side length of the regular tetrahedron.

Eight regular tetrahedra can be placed in a ring which rotates freely, and the number can be reduced to six for squashed irregular tetrahedra (Wells 1975, 1991). Let a tetrahedron be length on a side, and let its base lie in the plane with one vertex lying along the positive -axis.
