How to control 64 LEDs without using 64 individual wires? Multiplexing! Running a wire to the anode of each led would obviously be impractical, and would look really bad.One way to get around this, is to split the cube into 4 layers of 16×16 LEDs All the LEDs aligned in a vertical column share a common anode (+) All the LEDs on a horizontal layer share a common cathode (-)
