## isovolume problemWhat surface encloses the maximum volume per unit surface? The answer is a sphere, for which: r^{ 3})/(4πr^{
2}) = 1/3r
where r is the sphere's radius. Proof of the solution to the isovolume
problem came as recently as 1882 from Schwarz. ## Related entries• bubbles• isoperimetric equality ## Related category• GEOMETRY | |||||
