# 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

The volume of the tetrahedron can be found by using the following formula :

Volume = a

^{3}/(6√2)

**Examples :**

Input : side = 3 Output : 3.18 Input : side = 20 Output : 942.81
