The base of a regular octahedron will be in the square shape. When two faces touch each other, the line segment that is formed is called an edge. The given below is the octahedron volume formula which helps you by providing an answer to your question of "How to find the volume of octahedron?". To know the capacity of octahedron just divide the square root of 2 by the integer 3 and multiply the resultant value with the cube value of edge length.
The above octahedron volume formula in this page will be a very useful one for mid and high-grade school students to refer for their examination purpose. This formula needs only basic mathematic operations to get the results.
