Definition: Volume(3D)

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
Since different three-dimensional objects have different shapes, their volumes are also variable. Let us look at some three-dimensional shapes and learn how to calculate their volume(V).

Explanation: The simplest and most common type of three-dimensional shape is a sphere. Some examples of spheres that we see in daily life include balls, globes, decorative lights, oranges, etc.

Tip Volume(3D)

The volume is expressed in cubic units, such as cubic centimeters (cm³), cubic meters (m³), cubic inches (in³), or cubic feet (ft³), depending on the unit system used.
