1. What is the Total Surface Area of Rhombic Triacontahedron?

The Total Surface Area of a Rhombic Triacontahedron is the total area of all its 30 rhombic faces. It is a Catalan solid with icosahedral symmetry, often studied in geometry and crystallography.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TSA = 12 \times \left( \frac{5 \times r_m}{5 + \sqrt{5}} \right)^2 \times \sqrt{5} \]

Where:

\( TSA \) — Total Surface Area of Rhombic Triacontahedron (m²)
\( r_m \) — Midsphere Radius of Rhombic Triacontahedron (m)
\( \sqrt{5} \) — Square root of 5 (approximately 2.23607)

Explanation: This formula calculates the total surface area based on the midsphere radius, utilizing the geometric properties of the rhombic triacontahedron.

3. Importance of Surface Area Calculation

Details: Calculating the surface area of geometric solids is essential in various fields including mathematics, engineering, material science, and architecture for understanding physical properties and spatial relationships.

4. Using the Calculator

Tips: Enter the midsphere radius in meters. The value must be positive and valid. The calculator will compute the total surface area using the precise mathematical formula.
