In geometry, a tetrahedron is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces.
Length of edge (a): 1.00
Volume: (√2)/12 × a³ = 0.12
Surface area: √3 × a² = 1.73
Number of vertices: 4
Number of edges: 6
Number of faces: 4
Base shape: Triangle
