There is no relationship whatsoever between the size
and weight of an object.
It's true that if you have ONE object, then cutting it in half
reduces its weight by half, and adding another identical object
to it doubles its weight.
But if I simply tell you the size of an object in my house, then
you have no way to estimate its weight. And vice versa ... if
I tell you its weight, you have no way of guessing its size.
