How does the Icosahedron Calculator work?

Volume = (5 × (3 + √5) / 12) × a³ where a = edge length Then: Surface area = 5 × √3 × a² Then: Circumradius = a × φ × √(φ) / 2 where φ = golden ratio (1.618...) Then: Has 20 equilateral triangle faces, 12 vertices.

Can you give an example of how to use the Icosahedron Calculator?

Example: Input edge=3 gives a result of Vol 131.59.

Is the Icosahedron Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
