Problem Statement

A cardboard box in the shape of a rectangular parallelopiped is to be enclosed in a cylindrical container with a hemispherical lid. If the total height of the container from the base to the top of the lid is 6060 centimetres and its base has radius 3030 centimetres, find the volume of the largest box that can be completely enclosed inside the container with the lid on.
