Can someone please help me answer this astronomy question?

Question

What would your mass be if you were composed entirely of neutron-star material of density 3*10^17 kg/m^3? (Assume that you average density is 100 kg/m^3.) Compare your answer with the mass of a typical 10-km-diameter rocky asteroid.

Answer 1

Mallard is being unhelpful.  To answer the q we need to know a typical human body volume.

I'm worried about the 100kg/m^3 density figure u state.

forgive me if i check out its sensibility by

assuming the human body density is about that of water

and water density is best remembered as 1g/cm^3

- and converting that to kg/m^3  in two stages we get :

      1kg / 10x10x10 cm cube

1000kg / 100x100x100 cm cube    - which is 1m cube

as i thought:

the density should be 1000kg/m^3

Answer 2

That's not an astronomy question; it's a physics question.

Answer 3

We could use more info to start with, but I'll assume that you're talking about an original mass. Let's say that it's 5,000 kg. If the material making up that mass were the same as that of neutron stars the mass would still be the same. Remember, mass is a measure of how much stuff is contained within some given volume. In this case the only thing that's changed is volume, not mass.
