The video tutorial explains how to apply Pythagoras' theorem in three dimensions using a cuboid. It involves identifying right triangles within the cuboid to calculate the length of a diagonal. The process includes finding the length of one side using Pythagoras' theorem and then using that result to find the final diagonal length. The tutorial demonstrates the step-by-step calculation, ensuring a clear understanding of the geometric principles involved.
