A hot air balloon plus cargo has a mass of 291 kg and a volume of 809 m3. The balloon is floating at a constant height of 6.25 m above the ground. The density of the outside air may be assumed to be 1.29 kg/m3. What is the density of the hot air in the balloon?(adsbygoogle = window.adsbygoogle || []).push({});

can someone help me with this problem? i know that i need to use the buoyant force but i'm not sure how to relate the height with the density
