1. What is the Volume of Pentakis Dodecahedron?

The Pentakis Dodecahedron is a Catalan solid derived from the dodecahedron by placing a pyramid on each face. Its volume represents the three-dimensional space enclosed by its surface, calculated based on its total surface area.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{15}{76} \times (23 + 11\sqrt{5}) \times \left( \frac{19 \times TSA}{15 \times \sqrt{413 + 162\sqrt{5}}} \right)^{\frac{3}{2}} \]

Where:

Explanation: This formula relates the volume of a Pentakis Dodecahedron to its total surface area through a precise mathematical relationship involving the golden ratio constant.

3. Importance of Volume Calculation

Details: Calculating the volume of geometric solids is fundamental in mathematics, engineering, architecture, and various scientific fields where spatial measurements and capacity calculations are required.

4. Using the Calculator

Tips: Enter the total surface area in square meters. The value must be positive and valid. The calculator will compute the corresponding volume of the Pentakis Dodecahedron.
