TETRAHEDRON

 TETRAHEDRON:

A tetrahedron is a third dimensional structure having 4 triangles as faces, six edges and four vertices. 

A tetrahedron is also called a triangular pyramid. 

 In a tetrahedron if all four triangles are equilateral triangles then the tetrahedron is called a regular tetrahedron.

The volume of a tetrahedron is one-third the area of the base times the height i.e. volume V= (1/3)bh, where b is base and h is height.

Also the total surface area is the sum of the surface areas of all it's faces.

Here We see some properties of a regular tetrahedron.

 Volume = a^3/6√2

Total surface area= (a^2)√3

surface area of each face = (1/4)(a^2)√3

Height =a√6/3,

                            here a is the side of regular tetrahedron.
