Dear Hannah, you can simply use the direct formula for the center of mass: x = (m1*x1 + m2*x2 + m3*x3)/(m1+m2+m3), where m1=5, m2=3, m3 = 2 (quantity of cubes on each cell along X) and x1=0.5*L, x2=1.5*L, x3=2.5*L respectively. So we'll get x=1.2L
ok but WHY. what is x?? why do we set 5x = to the others, we learned center of mass was adding them all together and then dividing by total mass. Why is it being set equal?
