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

The Total Surface Area of a Rhombic Dodecahedron is the total area of all its twelve rhombic faces. It represents the complete outer surface measurement of this three-dimensional polyhedron.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TSA = 12 \times \sqrt{2} \times r_i^2 \]

Where:

Explanation: This formula calculates the total surface area based on the radius of the inscribed sphere (insphere) that touches all faces of the rhombic dodecahedron.

3. Importance of Surface Area Calculation

Details: Calculating the total surface area is crucial for various applications including material estimation, heat transfer calculations, coating requirements, and geometric analysis of this specific polyhedral structure.

4. Using the Calculator

Tips: Enter the insphere radius in meters. The value must be positive and greater than zero. The calculator will compute the total surface area in square meters.

5. Frequently Asked Questions (FAQ)
