1. What is Edge Length of Truncated Rhombohedron?

The Edge Length of Truncated Rhombohedron is the length of the edge that joins the triangular edge with rhombohedral edges on each face of the Truncated Rhombohedron. It is a fundamental geometric measurement in solid geometry.

2. How Does the Calculator Work?

The calculator uses the mathematical formula:

\[ l_e = \frac{\sqrt{\frac{4 \times A_{Pentagon}}{\sqrt{5 + 2\sqrt{5}}}}}{2} \times (3 - \sqrt{5}) \]

Where:

Explanation: This formula calculates the edge length based on the area of the pentagonal face, using mathematical constants and square root functions.

3. Importance of Edge Length Calculation

Details: Calculating the edge length is essential for understanding the geometric properties of truncated rhombohedrons, including volume, surface area, and other dimensional relationships in solid geometry applications.

4. Using the Calculator

Tips: Enter the area of the pentagon in square meters. The value must be positive and greater than zero for accurate calculation.
