What is the formula for calculating the volume of a rectangle?

The formula for calculating the volume of a rectangle is length times width times height, represented as HxWxL. This formula allows you to determine the three-dimensional space that a rectangular prism occupies. By multiplying these three dimensions, you can obtain the volume, which is typically expressed in cubic units, such as cubic meters or cubic feet.

The significance of this formula lies in its application in various fields, including water treatment, where understanding the volume of tanks or containers is crucial for appropriate chemical dosing and effective system design. The other options do not pertain to calculating volume; they either describe circular area, concentration of substances, or operational procedures related to equipment functionality, none of which directly address the volume of a rectangular space.
