23 × sqrt(25 + 10 × sqrt(5)) × 2²(15 + 7 × sqrt(5)) / 4 × 2³
33 × sqrt(25 + 10 × sqrt(5)) × 3²(15 + 7 × sqrt(5)) / 4 × 3³
43 × sqrt(25 + 10 × sqrt(5)) × 4²(15 + 7 × sqrt(5)) / 4 × 4³
53 × sqrt(25 + 10 × sqrt(5)) × 5²(15 + 7 × sqrt(5)) / 4 × 5³

Example of Dodecahedron Calculator

Let's consider a dodecahedron with an edge length of 5 cm. Using our calculator, the surface area and volume would be computed as follows:

  • Surface Area: A = 3 * sqrt(25 + 10 * sqrt(5)) * (5)^2
  • Volume: V = (15 + 7 * sqrt(5)) / 4 * (5)^3
