1. What is Pyramidal Height of Great Dodecahedron?

The Pyramidal Height of Great Dodecahedron is the height of any of the inwards directed tetrahedral pyramids of the Great Dodecahedron. It is a key geometric parameter that helps define the three-dimensional structure of this complex polyhedron.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ h_{Pyramid} = \frac{\sqrt{3} \cdot (3 - \sqrt{5})}{6} \cdot \frac{15 \cdot \sqrt{5 - (2 \cdot \sqrt{5})}}{\frac{5}{4} \cdot (\sqrt{5} - 1) \cdot \frac{A}{V}} \]

Where:

\( h_{Pyramid} \) — Pyramidal Height of Great Dodecahedron (m)
\( \frac{A}{V} \) — Surface to Volume Ratio of Great Dodecahedron (m⁻¹)
\( \sqrt{3} \) — Square root of 3 (approximately 1.732)
\( \sqrt{5} \) — Square root of 5 (approximately 2.236)

Explanation: The formula relates the pyramidal height to the surface to volume ratio through a complex mathematical relationship involving square roots and geometric constants specific to the Great Dodecahedron.

3. Importance of Pyramidal Height Calculation

Details: Calculating the pyramidal height is essential for understanding the internal structure and geometric properties of the Great Dodecahedron. It helps in architectural design, mathematical modeling, and studying the spatial relationships within this complex polyhedron.
