Find the volume of a regular tetrahedron of side 35cm

Therefore the Volume of a Regular Tetrahedron of side 35 cm is

5028.87 cm³.

Step-by-step explanation:

Regular Tetrahedron :

A regular tetrahedron is one in which all four faces are equilateral triangles.

There are a total of 6 edges in regular tetrahedron, all of which are equal in length. \

There are four vertices of regular tetrahedron, 3 faces meets at any one vertex.

Given:

Side = edge = a = 35 cm

To Find:

volume of a regular tetrahedron = ?

Solution:

Volume of a Regular Tetrahedron is given as

Where, a = edge

Substituting the values we get

Therefore the Volume of a Regular Tetrahedron of side 35 cm is

5028.87 cm³.

thus, the first answer choice, y = sec x, is the correct one
