# Program to calculate area and volume of a Tetrahedron

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 area of Tetrahedron can be found by using the formula :

Area = sqrt(3)*(side*side)

Examples :

Input : side = 3
Output : 15.5885

Input : side = 20
Output : 692.82

Output :

Area of Tetrahedron =15.5885

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

## C/C++

 // CPP program to find the volume of a tetrahedron #include #include    // Function to calculate volume double vol_tetra(int side) {     double volume = (pow(side, 3) / (6 * sqrt(2)));     return volume; }    // Driver Code int main() {     int side = 3;     double vol = vol_tetra(side);     printf("%.2f", vol); }

## Java

 // Java code to find the volume of a tetrahedron import java.io.*;    class Tetrahedron {     // Function to calculate volume     static double vol_tetra(int side)     {         double volume = (Math.pow(side, 3) / (6 * Math.sqrt(2)));         return volume;     }        // Driver Code     public static void main(String[] args)     {         int side = 3;         double vol = vol_tetra(side);         vol = (double)Math.round(vol * 100) / 100;         System.out.println(vol);     } }

## Python

 # 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)
