To determine the volume of air that needs to be dehumidified in a space, the correct factor to use is the cubic measurement of the area, which is calculated by multiplying the length, width, and height of the room. This provides the total volume in cubic feet.

Using cubic feet is crucial because it gives a standardized measurement for understanding how much air is present in the area that will require dehumidification. Once the cubic footage is established, this information can be used to select appropriately sized dehumidification equipment and to assess the overall moisture load within the space.

In the context of the other options, air temperature and humidity factor do not provide a volume measurement; instead, they influence how moisture interacts with the air. Room dimensions alone do not represent the calculated volume; they need to be combined (length x width x height) to obtain the cubic feet of air in the room. Therefore, knowing the cubic feet is essential for proper calculations in the restoration and dehumidification process.
