After discussing volume as a type of measurement that quantifies the capacity of a 3D figure, filling the shape with tiny cubes, we cover the various formulae associated with polyhedra, which are 3D shapes whose faces are polygons.  Duration: 11:03

Examples of solids of revolution include cylinders, cones, and spheres, and they are characterized by having smooth curves rather than sharp edges like polyhedra.  Here we take a look at the volume formulae of these 3D shapes.  Duration: 6:57
