Practice for the quiz:
Know, and be able to write intelligently, about the 4D cube.
Questions:
1. How do you make a 4D cube (or make a 3D shadow of a 4D cube)?
2. How many vertices does a 4D cube have?
3. Tell how you can use the number of vertices a 3D cube to find the number of vertices on a 4D cube, and explain why that strategy makes sense.
4. How many edges does a 4D cube have?
5. Tell how you can use the number of edges and vertices on a 3D cube to find the number of edges on a 4D cube, and explain why that strategy makes sense.
