Answer:
volume of air = 3200 m³
Explanation:
We are given that 1 m³ of hot air can lift a mass of about 0.25 kg.
To find the volume of hot air required to lift a mass of 800 kg, we will simply use cross multiplication as follows:
1 m³ ..................> 0.25 kg
?? .....................? 800 kg
volume of hot air required = (800*1) / (0.25)
volume of hot air required = 3200 m³
Hope this helps :)
