I got this question in an interview for internship.

This intriguing question comes from Centroid of a Body in portion Centre of Gravity and Centroid of Engineering Mechanics

Answer 1

The correct option is (d) Volume

To explain I would say: The product of the centroid of the section to its volume to the total volume of the body is the centre of volume. Thus the answer. The ratio is generally used to locate the coordinate of the centroid or the centre of volume.
