## Python program to find the Volume of a Tetrahedron:

In this post, we will learn how to find the *volume* of a *regular Tetrahedron* in python. Tetrahedron is a triangular pyramid. It has four triangular faces and *six* edges.

If its faces are *equilateral triangles*, it is called a *regular tetrahedron*. All edges are of equal lengths and all faces have same *size* and *shapes*.

### Volume of a Tetrahedron:

The *volume of a regular tetrahedron* is defined as below:

`a3/(6√2)`

Where, *a* is the length of its sides. The length of all edges are equal since it is a *regular tetrahedron*.

So, if we can read the *length of a side* as input from the user, we can calculate its volume.

### Python program:

We will write one *python program* that will take the length of the edges of the *regular tetrahedron* as input from the user and print the *volume*.

Below is the complete python program:

```
import math
def find_volume(a):
return (a ** 3 / (6 * math.sqrt(2)))
if __name__ == '__main__':
side_length = float(input('Enter the length of the sides: '))
print('Volume: {:.2f}$'.format(find_volume(side_length)))
```

Here,

*find_volume*method is used to find the volume of a*regular tetrahedron*.- This method takes the length of the edges as the parameter and returns the volume.

### Sample output:

If you run this program, it will print outputs as like below:

```
Enter the length of the sides: 5
Volume: 14.73$
Enter the length of the sides: 5.23
Volume: 16.86$
Enter the length of the sides: 11.24
Volume: 167.35$
```
