Mathematics for elementary through high school students.
Lesson 3: 3D Geometry
This video uses a 3-D shape builder to describe the orientation of 3-D shapes. The important thing to remember is that since there are three dimensions, there will be three measurements: length, width, and height.
This video covers how to find the surface area and volume of cones, cylinders, and rectangular prisms along with cubes. A good rule of thumb is to take the area of the base (whatever shape it may be) and multiply that by the height of the shape to get the volume.
