3D Pythagorean Theorem Applications

Eddie the Magic Monk explains how to use Pythagoras' theorem to find the hypotenuse of a triangle in a 3D rectangular prism. He demonstrates both a long and a short method for calculating the hypotenuse, using a step-by-step approach. The tutorial includes drawing a 3D prism, visualizing the problem, and applying Pythagoras' theorem to solve for the hypotenuse. The final result is calculated as the square root of 174, approximately 13.19 units.
