A cuboid is a rectangular parallelepipedon. By the notion ''stationary
Poisson cuboid process'' we understand a stationary Poisson hyperplan
e process which divides the Euclidean space R(d) into cuboids. It is e
quivalent to speak of a stationary Poisson cuboid tessellation. The di
stributions of volume and total edge length of the typical cuboid and
the origin-cuboid of a stationary Poisson cuboid process are considere
d. It is shown that these distributions become minimal, in the sense o
f a specific order relation, in the case of quasi-isotropy. A possible
connection to a more general problem, treated in [6], is also discuss
