Volume is a measure of regions in three-dimensional space. It is often quantified numerically using SI derived units (such as the cubic metre and litre) or by various imperial or US customary units (such as the gallon, quart, cubic inch). The definition of length and height (cubed) is interrelated with volume.
Here's more on about volume
Volume refers to the amount of space occupied by a three-dimensional (3-D) object or the level of sound measured in decibels. In science, volume is often expressed in units such as liters (L), milliliters (mL), or cubic centimeters (cm³). In music, volume is a measure of the loudness of sound, with higher decibel levels indicating greater volume. In everyday language, volume can also refer to the quantity or extent of something, such as the volume of traffic or the volume of a conversation. Understanding volume is essential in various fields, including physics, acoustics, and communication.
