Abstract: In this note we prove that the intrinsic $i$-volume of any $d$-dimensional zonotope generated by $d+1$ (resp. $d$) line segments and containing a $d$-dimensional unit ball in $\bf{E}^d$ is at least as large as the intrinsic $i$-volume of the $d$-dimensional regular zonotope generated by $d+1$ line segments having inradius 1, where $i=1,\dots,d-1,d$.
Keywords: zonotopes, parallelohedra, rhombic dodecahedra, lattice sphere packings
