SUMMARY
The discussion clarifies that the volume of a sphere is mathematically determined by the formula V = (4/3)πR³, establishing that a planet with half the radius of Earth possesses less than half the volume. Specifically, if the radius is halved, the volume and mass decrease to one-eighth of the original values. The relationship between dimensions and volume is geometrical, with a doubling of dimensions resulting in an eightfold increase in volume and mass, while halving dimensions leads to an eightfold decrease.
