only one

Answer 2

For a cubical box containing assorted sweets, the center of mass is not at the geometrical center. (Option C)

• Objects having a mass that is not concentrated at the center of the body cannot have their geometrical center as their center of mass.
• Because their mass is concentrated at the center of the body, an egg and a cylindrical box full of rice have their centers of mass at the geometrical center.
• Because the mass of a cubical box containing assorted sweets is not concentrated at the center of the body, the center of mass of a cubical box holding various sweets is not at the geometrical center.
