Answer:

Yes. But lets skip that for now. 2D arrays are usually as high as you need to go. 3D arrays get very big. A 3D array of 100 sheets of 2D arrays, where each 2D array has 100 rows and 100 columns would have 100*100*100 cells, 1,000,000 cells. That is an awful lot of data. Usually some other type of data structure would be used.
