Last Updated :
23 Jul, 2025
Volume refers to the amount of space occupied by a three-dimensional object. In geometry, calculating the volume is essential for understanding the capacity of a shape. It is used in various fields like engineering, architecture, and manufacturing to determine the amount of material or space an object can hold.
Volume formulas are mathematical tools used to calculate the space inside 3D geometric shapes. Each shape, such as a cube, sphere, or cone, has its own specific formula for determining its volume.
Volume FormulasThe following table contains a comprehensive list of all the volume formulas of different 3D shapes.
