1. What is Face Perimeter of Dodecahedron?

The Face Perimeter of a Dodecahedron is the total distance around the five edges of any face of the Dodecahedron. It is an important geometric measurement in understanding the properties of this polyhedron.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P_{Face} = \frac{60 \times \sqrt{25 + 10 \times \sqrt{5}}}{R_{A/V} \times (15 + 7 \times \sqrt{5})} \]

Where:

\( P_{Face} \) — Face Perimeter of Dodecahedron (m)
\( R_{A/V} \) — Surface to Volume Ratio of Dodecahedron (1/m)
\( \sqrt{} \) — Square root function

Explanation: This formula calculates the face perimeter based on the surface to volume ratio of a regular dodecahedron, utilizing mathematical constants related to its geometry.

3. Importance of Face Perimeter Calculation
