1. What is the Edge Length of Rhombic Triacontahedron?

The Edge Length of Rhombic Triacontahedron is the length of any of the edges of a Rhombic Triacontahedron or the distance between any pair of adjacent vertices of the Rhombic Triacontahedron.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Edge\ Length = \frac{5 \times Midsphere\ Radius}{5 + \sqrt{5}} \]

Where:

\( Midsphere\ Radius \) — The radius of the midsphere of the Rhombic Triacontahedron (m)
\( \sqrt{5} \) — Square root of 5 (approximately 2.23607)

Explanation: This formula calculates the edge length of a Rhombic Triacontahedron based on its midsphere radius, using the mathematical relationship between these two geometric properties.

3. Importance of Edge Length Calculation

Details: Calculating the edge length is essential for understanding the geometric properties of the Rhombic Triacontahedron, including its surface area, volume, and other dimensional characteristics in geometric modeling and 3D design applications.

4. Using the Calculator

Tips: Enter the midsphere radius in meters. The value must be positive and valid for accurate calculation of the edge length.

5. Frequently Asked Questions (FAQ)

Q1: What is a Rhombic Triacontahedron?
A: A Rhombic Triacontahedron is a convex polyhedron with 30 rhombic faces. It's one of the Catalan solids and is the dual polyhedron of the icosidodecahedron.

Q2: What is the midsphere radius?
A: The midsphere radius is the radius of the sphere that is tangent to all the edges of the polyhedron.

Q3: Can this formula be used for other polyhedra?
A: No, this specific formula applies only to the Rhombic Triacontahedron as it describes the unique relationship between edge length and midsphere radius for this particular polyhedron.

Q4: What are practical applications of this calculation?
A: This calculation is used in crystallography, architectural design, 3D modeling, and mathematical research involving polyhedral geometry.

Q5: How accurate is this calculation?
