1. What is the Long Edge of Pentagonal Hexecontahedron?

The Long Edge of Pentagonal Hexecontahedron is the length of the longest edge which is the top edge of the axial-symmetric pentagonal faces of Pentagonal Hexecontahedron. It is a crucial geometric measurement in this complex polyhedral structure.

2. How Does the Calculator Work?

The calculator uses the mathematical formula:

\[ Long Edge = (Short Edge \times \sqrt{2+2 \times 0.4715756}) \times \frac{(7 \times \phi + 2) + (5 \times \phi - 3) + 2 \times (8 - 3 \times \phi)}{31} \]

Where:

\( Short Edge \) — Short Edge of Pentagonal Hexecontahedron (m)
\( \phi \) — Golden ratio constant (≈1.618034)
\( \sqrt{} \) — Square root function

Explanation: This formula establishes a precise mathematical relationship between the short and long edges of the pentagonal hexecontahedron using the golden ratio and specific coefficients.
