1. What is the Leg Length of Pentakis Dodecahedron?

The Leg Length of Pentakis Dodecahedron refers to the length of the equal sides of the isosceles triangular faces that make up this polyhedron. It is a key geometric parameter in understanding the structure and properties of the Pentakis Dodecahedron.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ Leg\ Length = \frac{3}{38} \times (9 + \sqrt{5}) \times \left( \frac{76 \times Volume}{15 \times (23 + 11 \times \sqrt{5})} \right)^{\frac{1}{3}} \]

Where:

\( Volume \) — Volume of the Pentakis Dodecahedron (m³)
\( \sqrt{5} \) — Square root of 5 (approximately 2.23607)

Explanation: This formula calculates the leg length based on the volume of the Pentakis Dodecahedron, using mathematical constants and operations including cube root and square root functions.

3. Importance of Leg Length Calculation

Details: Calculating the leg length is essential for geometric analysis, architectural design, and understanding the spatial properties of the Pentakis Dodecahedron. It helps in determining proportions and relationships between different elements of this complex polyhedron.

4. Using the Calculator

Tips: Enter the volume of the Pentakis Dodecahedron in cubic meters. The value must be positive and valid. The calculator will compute the corresponding leg length.

5. Frequently Asked Questions (FAQ)

Q1: What is a Pentakis Dodecahedron?
A: A Pentakis Dodecahedron is a Catalan solid that can be seen as a dodecahedron with a pyramid on each face. It has 60 isosceles triangular faces.

Q2: Why is this formula specific to Pentakis Dodecahedron?
