Understanding Volume

Volume measures the amount of space that an object occupies in three dimensions. For rectangular objects (boxes, rooms, containers), volume represents the total capacity or the amount of material needed to fill the space.

Rectangular Volume Formula:

Volume = Length × Width × Height

Common Applications

Everyday Use

  • • Storage box capacity calculation

Volume vs. Capacity

While often used interchangeably in everyday contexts, there's a technical distinction:

Volume

The amount of space an object itself occupies, including the material it's made from.

Capacity

The amount of substance a container can hold, considering wall thickness and internal space.

Other Volume Formulas

Different geometric shapes have their own volume formulas:

Sphere

V = (4/3)πr³

Cylinder

V = πr²h

Cone

V = (1/3)πr²h
