    54 minutes

    Step-by-step explanation:

    From the question, we are given;

    A room with dimensions 5.2 m by 4.3 m by 2.9 m The exchange air rate is 1200 L/min

    We are required to determine the time taken to exchange the air in the room;

    First we are going to determine the volume of the room;

    Volume of the room = length * width * height

    = 5.2 m * 4.3 m * 2.9 m

    = 64.844 m³

    Then we should know, that 1 m³ = 1000 L

    Therefore, we can convert the volume of the room into L

    = 64.844 m³ * 1000 L

    = 64,844 L

    But, the rate is 1200 L/min

    Thus, time = Volume : rate

    = 64,844 L : 1200 L/min

    = 54.0367 minutes

    = 54 minutes

    Therefore, it would take approximately 54 minutes
