My reasoning: So the equation for CM= M1XI +M2X2 + M3X3/ TM ... where M= mass, and X= distance ...So M(l +2l +3l)/3m = CM

M(6L)/3m = 2L

So, I got the center of Mass is 2L

I don't think my answer is correct, and even if my approach is correct. It is labeled a pretty easy problem, but I get really confused with problems without numbers. Also, I am not sure if you can conclude the total mass is 3M considering that means all the cubes would have to be the same mass ... and I also do not know what the question maker meant when he wrote the l=2l cube in the center ...

Please help!
