# Tetrahedron Calculator

## Definition

Tetrahedron - a three dimensional geometrical figure that consists of four triangular sides that form four vortexes and 6 edges.

Equation form:

height of tetrahedron(h) = | √6 * a |

3 |

Surface Area (SA) = √3 * a² |

Volume (V) = | √2 * a³ |

12 |

_{C}) of circumscribed sphere about tetrahedron with edge a:

V_{C} = | √6 * π * a³ |

8 |

_{I}) of inscribed sphere in tetrahedron with edge a:

V_{I} = | √6 * π * a³ |
