Understanding Geodesic Domes

What are Geodesic Domes?

Geodesic domes are spherical structures composed of a network of triangles that approximate a sphere or hemisphere.

Key Formulas

  • Surface Area = 4πr² × coverage
  • Volume = (4/3)πr³ × coverage
  • Number of Struts = 30v² × coverage
  • Number of Vertices = (10v² + 2) × coverage
  • Number of Faces = 20v² × coverage
