Euler's Formula and Polyhedra Concepts

This video tutorial introduces the concept of poliedros and Euler's relation, exploring various geometric shapes such as cubes, tetraedros, and prisms. The instructor explains the properties of these shapes, including their vertices, faces, and edges, and demonstrates how to apply Euler's relation to solve problems. The video concludes with exercises to reinforce the learning objectives.
