1. What is the Edge Length of Icosidodecahedron?

The edge length of an icosidodecahedron is the length of any edge of this Archimedean solid, which has 20 triangular faces and 12 pentagonal faces. It is a key geometric parameter for various calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( l_e \) — Edge Length of Icosidodecahedron (m)
• \( A_{Triangle} \) — Triangular Face Area of Icosidodecahedron (m²)

Explanation: This formula calculates the edge length based on the area of the triangular faces, utilizing the relationship between edge length and face area in this specific polyhedron.

3. Importance of Edge Length Calculation

Details: Calculating the edge length is essential for determining other geometric properties of the icosidodecahedron, such as surface area, volume, and for applications in architecture, modeling, and mathematical analysis.

4. Using the Calculator

Tips: Enter the triangular face area in square meters. The value must be positive and greater than zero.
