Volume of Icosahedron given Circumsphere Radius Calculator

Calculate Volume



Formula

The formula to calculate the Volume of an Icosahedron (\(V\)) is:

\[ V = \frac{5}{12} \times (3 + \sqrt{5}) \times \left(\frac{4 \times r_c}{\sqrt{10 + (2 \times \sqrt{5})}}\right)^3 \]

Where:

Definition

The Volume of an Icosahedron is the total quantity of three-dimensional space enclosed by the surface of the Icosahedron.

The Circumsphere Radius of an Icosahedron is the radius of the sphere that contains the Icosahedron in such a way that all the vertices are lying on the sphere.

How to calculate Volume of an Icosahedron given Circumsphere Radius

Let's assume the following value:

Using the formula:

\[ V = \frac{5}{12} \times (3 + \sqrt{5}) \times \left(\frac{4 \times 9}{\sqrt{10 + (2 \times \sqrt{5})}}\right)^3 \]

Evaluating:

\[ V = 1848.85386767778 \]

The Volume is 1848.8539 m³.
