There are centroid equations for common 2D shapes that we use as a shortcut to find the center of mass in the vertical and horizontal directions. If a 2D shape has curved edges, then we must model it using a function and perform a special integral. If it is a 3D shape with curved or smooth outer surfaces, then we must perform a multiple integral.
