1. What is Lateral Surface Area of Icosahedron?

The Lateral Surface Area of an Icosahedron is the total area of all the lateral faces (excluding the top and bottom faces) of this regular polyhedron. An icosahedron has 20 equilateral triangular faces, and its lateral surface area is calculated based on its space diagonal.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( LSA \) — Lateral Surface Area of Icosahedron (m²)
• \( d_{Space} \) — Space Diagonal of Icosahedron (m)
• \( \sqrt{} \) — Square root function

Explanation: The formula calculates the lateral surface area by relating it to the space diagonal of the icosahedron through geometric relationships.

3. Importance of Lateral Surface Area Calculation

Details: Calculating the lateral surface area is important in geometry, architecture, and material science for determining surface coverage, material requirements, and structural properties of icosahedral shapes.

4. Using the Calculator

Tips: Enter the space diagonal measurement in meters. The value must be positive and valid for accurate calculation.
