# Python Program for Program to calculate area of a Tetrahedron

• Difficulty Level : Basic
• Last Updated : 14 Aug, 2022

A Tetrahedron is simply a pyramid with a triangular base. It is a solid object with four triangular faces, three on the sides or lateral faces, one on the bottom or the base and four vertices or corners. If the faces are all congruent equilateral triangles, then the tetrahedron is called regular. The volume of the tetrahedron can be found by using the following formula :

Volume = a3/(6√2)

Examples :

```Input : side = 3
Output : 3.18

Input : side = 20
Output : 942.81```

## Python3

 `# Python code to find the volume of a tetrahedron``import` `math``def` `vol_tetra(side):``    ``volume ``=` `(side ``*``*` `3` `/` `(``6` `*` `math.sqrt(``2``)))``    ``return` `round``(volume, ``2``)` `# Driver Code``side ``=` `3``vol ``=` `vol_tetra(side)``print``(vol)`

Output :

`3.18`

Time complexity: O(1) since no loop is used the algorithm takes up constant time to perform the operations

Auxiliary Space: O(1)  since no extra array is used so the space taken by the algorithm is constant
