<H3>H I N T</H3>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The blocks that had purple paint on only one face, 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;are 2x2 = 4 &nbsp;blocks at &nbsp;EVERY &nbsp;face of the original &nbsp;4x4-cube.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;They are the blocks at every face that are not adjacent 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;the edges or the corners of the original 4x4-cube.



Therefore, &nbsp;to get the answer, &nbsp;you need to add &nbsp;2x2 = 4 &nbsp;small blocks 
as many times, &nbsp;as many faces you are interested in your exercise.
