     A  tetrahedron has four faces of an equilateral triangle. It can be constructed from joining four vertexes of a cube. If a cube centers at (0,0,0) with radius of unit, connect the vertexes of (1,1,1), (1,-1,-1), (-1,1,-1) and (-1,-1,1), a tetrahedron with volume equal to 4/3 units can be found.
