1. What is the Total Surface Area of Great Stellated Dodecahedron?

The Total Surface Area of a Great Stellated Dodecahedron is the total area of all its faces. It is a complex polyhedron with star-shaped faces, and its surface area calculation involves specific geometric relationships.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TSA = 15 \times \sqrt{5 + (2 \times \sqrt{5})} \times \left( \frac{6 \times h_{Pyramid}}{\sqrt{3} \times (3 + \sqrt{5})} \right)^2 \]

Where:

\( TSA \) — Total Surface Area of Great Stellated Dodecahedron (m²)
\( h_{Pyramid} \) — Pyramidal Height of Great Stellated Dodecahedron (m)
\( \sqrt{5} \) — Square root of 5 (approximately 2.23607)
\( \sqrt{3} \) — Square root of 3 (approximately 1.73205)

Explanation: This formula calculates the total surface area based on the pyramidal height, using mathematical constants and geometric relationships specific to the Great Stellated Dodecahedron.

3. Importance of Surface Area Calculation

Details: Calculating the surface area of complex polyhedra is important in geometry, architecture, and materials science. It helps in understanding spatial properties and material requirements for construction.

4. Using the Calculator

Tips: Enter the pyramidal height in meters. The value must be positive and greater than zero for accurate calculation.
