The Intrinsic Diameter of the Surface of a Parallelepiped

  • Y. G. Nikonorov
  • Y. V. Nikonorova


In the paper we obtain an explicit formula for the intrinsic diameter of the surface of a rectangular parallelepiped in 3-dimensional Euclidean space. As a consequence, we prove that an parallelepiped with relation \(1:1:\sqrt{2}\) for its edge lengths has maximal surface area among all rectangular parallelepipeds with given intrinsic diameter.
