Formulas
A copy turned over completes a cylinder of height h₁ + h₂, so this is exactly half of it: the mean height counts.
Checked: the V, L 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 can be stretched onto a sphere without tearing, so its Euler characteristic is 2. More on the lens.
