1. What is Total Surface Area of Pentagonal Icositetrahedron?

The Pentagonal Icositetrahedron is a Catalan solid with 24 pentagonal faces. Its total surface area represents the sum of the areas of all its pentagonal faces, providing a measure of the complete exterior surface of this three-dimensional geometric shape.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TSA = 3 \times \left(\frac{2 \times l_{long}}{\sqrt{[Tribonacci_C] + 1}}\right)^2 \times \sqrt{\frac{22 \times (5 \times [Tribonacci_C] - 1)}{(4 \times [Tribonacci_C]) - 3}} \]

Where:

\( TSA \) — Total Surface Area (m²)
\( l_{long} \) — Long Edge of Pentagonal Icositetrahedron (m)
\( [Tribonacci_C] \) — Tribonacci constant (≈1.839286755214161)

Explanation: This formula calculates the total surface area based on the long edge measurement, incorporating the mathematical constant specific to this geometric shape.

3. Importance of Surface Area Calculation

Details: Calculating the surface area of geometric solids is fundamental in various fields including architecture, materials science, and 3D modeling. It helps determine material requirements, heat transfer properties, and structural characteristics.

4. Using the Calculator

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