    The minimum volume of hot air needed to lift the hot air balloon is 653.06m³

    Step-by-step explanation:

    Density is defined as the ratio of the mass of a substance to its unit volume.

    Density = Mass/Volume

    Given mass of balloon = 800kg

    Density of air = 1.225 kg/m3 {standard value}

    Volume = Mass/Density

    Volume = 800/1.225

    Volume = 653.06m³

    The minimum volume of hot air needed to lift the hot air balloon is 653.06m³
