Can anyone name the 11 dimensions of M theory of the superstring theory and how is it possible to have 11 dimensions?

The first three are already know to you:

#1 Width

#2 Length

#3 Depth

#4 is Space/Time it is a combination of space and time, but at high energy states they can be separated.

The remaining 7 dimensions are not yet named or discovered, but string theory predict them using math. They are so small they cannot be seen, but gravity seems to work through them. They could be quantum dimensions and the reason why quantum theory has different laws than general relativity theory and larger scales.
