1. What is Rhombohedral Edge Length of Truncated Rhombohedron?

The Rhombohedral Edge Length of a Truncated Rhombohedron is the length of any edge of the original Rhombohedron from which the Truncated Rhombohedron is formed. It is a fundamental geometric parameter in crystallography and solid geometry.

2. How Does the Calculator Work?

The calculator uses the mathematical formula:

\[ le(Rhombohedron) = \frac{\frac{1}{2} \times (3 \times \sqrt{5 + 2 \times \sqrt{5}}) + 5 \times \sqrt{3} - 2 \times \sqrt{15}}{\frac{5}{3} \times \sqrt{\sqrt{5} - 2} \times \frac{RA}{V}} \]

Where:

\( le(Rhombohedron) \) — Rhombohedral Edge Length (m)
\( \frac{RA}{V} \) — Surface to Volume Ratio (1/m)
Mathematical constants and functions are used to derive the relationship

Explanation: This formula establishes the relationship between the surface to volume ratio and the original rhombohedral edge length of the truncated rhombohedron.

3. Importance of Rhombohedral Edge Length Calculation

Details: Calculating the original rhombohedral edge length is crucial for understanding the geometric properties of truncated rhombohedra, which have applications in crystallography, material science, and architectural design.

4. Using the Calculator

Tips: Enter the surface to volume ratio in 1/m. The value must be positive and valid for accurate calculation of the rhombohedral edge length.
