1. What is the Space Diagonal of Dodecahedron?

The Space Diagonal of a Dodecahedron is the line connecting two vertices that are not on the same face of the Dodecahedron. It passes through the interior of the solid and is an important geometric measurement for understanding the three-dimensional properties of this polyhedron.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ d_{Space} = \frac{\sqrt{3} \cdot (1 + \sqrt{5})}{2} \cdot \sqrt{\frac{TSA}{3 \cdot \sqrt{25 + 10\sqrt{5}}}}} \]

Where:

\( d_{Space} \) — Space Diagonal of Dodecahedron (m)
\( TSA \) — Total Surface Area of Dodecahedron (m²)
\( \sqrt{} \) — Square root function

Explanation: This formula derives the space diagonal length from the total surface area measurement using the mathematical relationships inherent in the dodecahedron's geometry.

3. Importance of Space Diagonal Calculation

Details: Calculating the space diagonal is crucial for understanding the complete spatial dimensions of a dodecahedron, which is important in various fields including geometry, architecture, material science, and 3D modeling.

4. Using the Calculator

Tips: Enter the total surface area in square meters. The value must be positive and valid. The calculator will compute the corresponding space diagonal length.
