Cubic and Hexagonal Close Packing?

Hi, I have an Inorganic Lab exam soon, and the practice test is asking how many neighbors spheres have in both hexagonal close packing (ABAB) and cubic close packing (ABCABC). It also asks which one leads to the face centered cubic unit cell. Thanks a lot! We don't have a textbook for this class and I am terrible at visualizing.

HCP and CCP both have 12 near neighbours.
CCP is the same as FCC.
