This geometry video tutorial provides a basic introduction into 3d shapes. It covers 3-dimensional figures such as cylinders, cones, rectangular prisms, triangular prisms, square pyramids, and cubes. It provides the equations and formulas needed to calculate the surface area and volume of these 3d shapes. It also explains how to determine the number of faces, edges, and vertices in a cube, triangular prism, and in a square based pyramid and how these values relate to euler's formula.
