Hi there! Hopefully this helps!
The volume of air = 2000 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 500 kg, we will use cross-multiplication as follows:
1 m³ ..................> 0.25 kg
?? .......................>500 kg
volume of hot air required = (500*1) / (0.25)
volume of hot air required = 2000 m³
