Formulas
With c = a it is a triangular prism, abh/2; with c = 0 it is a pyramid, abh/3. The formula runs between the two.
Checked: the V formula agrees with a Monte Carlo measurement of the shape itself, made from its geometric definition, every time the site is built.
Topology lens
Topologically a ball. Its surface has V = 6 vertices, E = 9 edges and F = 5 faces, and V − E + F = 2, as for every convex polyhedron (Euler, 1758). More on the lens.
