Archimedes' Principle says that when you displace some volume of fluid, you experience an upward force equal to the weight of the fluid displaced.

The problem boils down to finding out how much weight a metre of log can support.

Many physics A-Level syllabuses cover Archimedes' Principle, which is covered in more depth in most 1st year general engineering courses.
