How many vertices does a cube have? How do you know for sure?

A cube has 24. Each side has 4 vertices and there are 6 sides.
I hope this helps. Thanks for asking. 
Mmmmh, I have a picture cube in front of me that my wife has filled with pictures of the grandkids.
I can only count 6 corners. 
Although there are 6 sides, there are 8 corners — four on the top and four on the bottom. Each corner has 3 vertices, one for each side.
I hope this helps a little more. Thanks for asking.
