Right prisms with n sides. (a) Prisms with increasing n values at constant volume and fixed length L of aspect ratio γ = 3. Aspect ratio γ is defined as [L/(2R_{\rm {ave}})]. (b) The corresponding cross sections are regular polygons with identical areas. (c) Characteristic dimensions of the polygonal cross section illustrated for a pentagon (n = 5): E is the edge length, R is the circumradius of the regular polygon and [R_{\rm {ave}}] (in red) is the squared average radius. The arrows in dark blue and magenta correspond, respectively, to the vectors [{\bf M}_{j}] (middle of edges) and [{\bf E}_{j}] (half-edges) used in the form factor calculation in equation (5[link]).
