What factor is multiplied by the area's length, width, and height to determine the volume of air to dehumidify?

Cubic feet
Air temperature
Humidity factor
Room dimensions

The correct answer is: Cubic feet

To determine the volume of air that needs to be dehumidified in a specific space, it is essential to calculate the total volume in three dimensions: length, width, and height. The measurement of volume is expressed in cubic units, which in this case is cubic feet. By multiplying the area's length, width, and height, the result provides the total volume of air in the room. This measurement is crucial for effective water damage restoration and dehumidification processes, as it informs the technician of the amount of air that needs to be treated to achieve the desired humidity levels. Although room dimensions are indeed used to calculate the total volume, the answer specifically points to the unit of measurement, which is cubic feet. Air temperature and humidity factor, while important in the process of dehumidification, do not directly relate to determining the volume of air needing treatment; hence, they are not the appropriate choices.
