1. What is Face Diagonal of Dodecahedron?

The Face Diagonal of a Dodecahedron is defined as the distance between any pair of opposite corners on a particular pentagonal face of the Dodecahedron. It is an important geometric measurement in understanding the structure and properties of this polyhedron.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ d_{Face} = \frac{2}{\sqrt{3}} \times r_c \]

Where:

\( d_{Face} \) — Face Diagonal of Dodecahedron (m)
\( r_c \) — Circumsphere Radius of Dodecahedron (m)

Explanation: This formula calculates the face diagonal length based on the circumsphere radius of the dodecahedron, using the mathematical relationship between these two geometric properties.

3. Importance of Face Diagonal Calculation

Details: Calculating the face diagonal is crucial for understanding the geometry of dodecahedrons, which have applications in various fields including crystallography, architecture, and 3D modeling. It helps in determining the spatial relationships and proportions within this regular polyhedron.

4. Using the Calculator

Tips: Enter the circumsphere radius in meters. The value must be positive and valid. The calculator will compute the corresponding face diagonal length of the dodecahedron.

5. Frequently Asked Questions (FAQ)

Q1: What is a Dodecahedron?
A: A dodecahedron is a three-dimensional shape with twelve flat faces, each being a regular pentagon. It is one of the five Platonic solids.
