1. What is Midsphere Radius of Rhombic Triacontahedron?

The Midsphere Radius of a Rhombic Triacontahedron is the radius of the sphere that is tangent to all the edges of the polyhedron. It represents the sphere that touches every edge of the Rhombic Triacontahedron at exactly one point.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ r_m = \sqrt{\frac{TSA}{12\sqrt{5}}} \times \frac{5+\sqrt{5}}{5} \]

Where:

Explanation: This formula calculates the midsphere radius based on the total surface area of the Rhombic Triacontahedron, using mathematical constants and geometric relationships specific to this polyhedron.

3. Importance of Midsphere Radius Calculation

Details: Calculating the midsphere radius is important in geometry and crystallography for understanding the spatial properties and symmetry of the Rhombic Triacontahedron, which has applications in material science and structural design.

4. Using the Calculator

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