Volume and Surface Area Formulas

This video tutorial covers various 3D shapes, including spheres, cylinders, cones, rectangular prisms, triangular prisms, square pyramids, and cubes. It explains how to calculate their volume and surface area, and discusses the number of faces, edges, and vertices for each shape. The video also introduces Euler's formula and demonstrates its application to these shapes.
