these are simple conversion problems.
the first one you calculate the density in km/kg then convert. or you can convert first then calculate. That might be easier.
you have to know the conversion factors though. km^3 to cm^3 is what you want because 1cm^3 = 1ml. remember that 1000 meters is one km and 100 cm is 1 m. then don’t forget to cube them.
converting kg to g is simply dividing by 1000.
Good luck.
