What formula is used to calculate the volume of a room?

The formula to calculate the volume of a room is given by V = L x W x H, where L represents the length, W is the width, and H is the height of the room. Volume is a measure of how much three-dimensional space an object occupies, and for a rectangular room, it is determined by multiplying the three dimensions together. This multiplication takes into account the entire space within the boundaries of the room.

In contrast, other formulas provided do not correctly represent the concept of volume. For instance, adding the dimensions or using addition with multiplication wouldn't yield the correct measure of space occupied. Volume specifically requires considering the extent in three dimensions, and thus the multiplication of all three dimensions reflects that spatial measurement accurately.
