PHYSICS...please help!

Four astronauts are in a spherical space station.

1) If, as is typical, each of them breathes about 500cm^3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year?

2) What would the diameter (in meters) of the space station have to be to contain all this air?

What is your try at the solution, jcz?
 


convert the cm^3 into m^3.
How many puffs do you take per minute? How many per year? The rest is simple arithmatic...
