1. What is the Total Surface Area of Pentagonal Trapezohedron?

The Total Surface Area of a Pentagonal Trapezohedron is the total quantity of two dimensional space enclosed on the entire surface of this geometric solid. It represents the sum of the areas of all its faces.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TSA = \sqrt{\frac{25}{2} \cdot (5 + \sqrt{5})} \cdot \left( \frac{l_{short}}{\frac{\sqrt{5} - 1}{2}} \right)^2 \]

Where:

\( TSA \) — Total Surface Area of Pentagonal Trapezohedron (m²)
\( l_{short} \) — Short Edge of Pentagonal Trapezohedron (m)
\( \sqrt{5} \) — Mathematical constant (approximately 2.23607)

Explanation: The formula calculates the total surface area based on the length of the short edge, incorporating the golden ratio properties inherent in pentagonal geometry.

3. Importance of Surface Area Calculation

Details: Calculating the total surface area is crucial for various applications including material estimation, structural analysis, and geometric properties studies of pentagonal trapezohedrons.

4. Using the Calculator

Tips: Enter the length of the short edge in meters. The value must be positive and greater than zero for accurate calculation.
