How is the volume (V) of a room calculated?

The volume of a room is calculated by multiplying its length, width, and height. This formula accounts for the three-dimensional space that the room occupies. Each dimension contributes to the overall capacity of the room, allowing one to determine how much air or material can fit within that space.

The formula can be seen as a geometric representation where length and width define the area of the base while height provides the third dimension, creating a volumetric measurement. Understanding this concept is crucial in various applications, such as ventilation, calculating heating or cooling requirements, and even in planning occupancy levels.

In contrast, the other options do not represent the correct method for calculating volume. For example, adding length, width, and height simply gives a total of the lengths of the dimensions but does not provide a measure of the space inside the room. Multiplying length and width gives the area of the floor but does not incorporate the height, which is essential for volume. Lastly, dividing height by the sum of length and width does not represent any structural or physical property relevant to volume calculation.
