1. What is the Total Surface Area of Icosidodecahedron?

The Total Surface Area of an Icosidodecahedron is the total quantity of plane enclosed by the entire surface of this Archimedean solid. An Icosidodecahedron has 20 triangular faces and 12 pentagonal faces, making it a polyhedron with 32 faces, 60 edges, and 30 vertices.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ TSA = \frac{(5\sqrt{3} + 3\sqrt{25 + 10\sqrt{5}}) \times P_{Pentagon}^2}{25} \]

Where:

\( TSA \) — Total Surface Area of Icosidodecahedron (m²)
\( P_{Pentagon} \) — Pentagonal Face Perimeter of Icosidodecahedron (m)
\( \sqrt{3} \) — Square root of 3 (approximately 1.732)
\( \sqrt{5} \) — Square root of 5 (approximately 2.236)

Explanation: This formula calculates the total surface area based on the perimeter of the pentagonal faces, incorporating mathematical constants specific to the geometry of the icosidodecahedron.

3. Importance of Surface Area Calculation

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

4. Using the Calculator

Tips: Enter the pentagonal face perimeter in meters. The value must be positive and greater than zero. The calculator will compute the total surface area using the mathematical formula.
