Final answer:
Volume refers to the amount of space within a container or the space a 3-dimensional object occupies, usually measured in cubic units like cubic meters.
Step-by-step explanation:
Volume refers to the amount of space within a container or the amount of space inside a 3-dimensional object. The volume is a measure of how much space an object occupies and is typically expressed in cubic units. When we talk about standard SI units of volume, we refer to the cubic meter (m³), which is a cube with an edge length of exactly one meter. For instance, to dispense a cubic meter of water, you could utilize a cubic box with dimensions of exactly one meter on each side. Understanding volume is crucial since it helps us in determining the 'size' of an object in a spatial context, which is essential for various applications in everyday life and various academic fields.
