A regular octahedron has 8 congruent triangular faces, 12 edges, and 6 vertices.
Its volume follows V= rac{sqrt{2}}{3}a^3, where is the common edge length.
Because the edge is cubed, small size changes create much larger volume changes.
Calculate the volume of a regular icosahedron from its edge length, then inspect related measures like surface area and circumradius.
Calculate the volume of a regular octahedron quickly and easily online.
Calculate the volume of a regular dodecahedron from its edge length, with supporting surface area, circumradius, and a compact solid preview.
