Three cubes, of side 0, 20, and 30, are placed next to one another (in contact) with their centers along a straight line as shown in the figure. What is the position, along this line, of the CM of this system? Assume the cubes are made of the same uniform material and 0 = 5.5 cm.

My bad. Retyping the question down here because the symbol didn't appear.

Three cubes, of side Lₒ, 2Lₒ, and 3Lₒ, are placed next to one another (in contact) with their centers along a straight line as shown in the figure. What is the position, along this line, of the CM of this system? Assume the cubes are made of the same uniform material and Lₒ = 5.5 cm.
