The volume formula is a mathematical expression that can be used to calculate the total amount of space (vacuum) occupied by any three-dimensional object.
The volume of an object is the amount of three-dimensional space occupied by the object or shape. It is typically measured in cubic units. In other words, the volume of any object or container is its ability to hold the amount of fluid (gas or liquid). Using arithmetic formulas, the volume of three-dimensional mathematical shapes such as the cube, cuboid, cylinder, prism, and cone, among others, can be easily calculated.
Cuboid Formula
V = l × w × h
l represent Length
w represent Width
h represent Height
