1. What is Pyramidal Edge Length of Triakis Icosahedron?

The Pyramidal Edge Length of Triakis Icosahedron refers to the length of the edges that form the pyramidal components attached to each face of the underlying icosahedron in a Triakis Icosahedron. This geometric measurement is crucial for understanding the structure and properties of this polyhedron.

2. How Does the Calculator Work?

The calculator uses the mathematical formula:

\[ l_{pyramid} = \frac{15 - \sqrt{5}}{22} \times l_{icosahedron} \]

Where:

\( l_{pyramid} \) — Pyramidal Edge Length (m)
\( l_{icosahedron} \) — Icosahedral Edge Length (m)
\( \sqrt{5} \) — Square root of 5 (approximately 2.23607)

Explanation: This formula establishes the precise mathematical relationship between the pyramidal edge length and the icosahedral edge length in a Triakis Icosahedron, derived from geometric principles and trigonometric relationships.

3. Importance of Pyramidal Edge Length Calculation

Details: Calculating the pyramidal edge length is essential for geometric analysis, 3D modeling, architectural design, and understanding the spatial properties of the Triakis Icosahedron. It helps in determining surface area, volume, and other geometric characteristics of this complex polyhedron.

4. Using the Calculator

Tips: Enter the icosahedral edge length in meters. The value must be positive and greater than zero. The calculator will compute the corresponding pyramidal edge length using the established mathematical relationship.
