What is the formula for volume?

The volume formula depends on the shape. For example: Cylinder = πr²h, Sphere = 4/3πr³, Cube = a³, Cone = 1/3πr²h, Rectangular solid = length × width × height.

How do I find the volume of a cylinder?

Use the cylinder volume formula V = πr²h, where r is the radius and h is the height. Enter the values into the cylinder volume calculator for an instant calculation.

How do you calculate tank volume?

Tank volume is calculated using length × width × height for rectangular tanks. A rectangular tank volume calculator can automatically compute the result once dimensions are entered.

Is this volume calculator free to use?

Yes, the volume calculator is completely free, works on all devices, and does not require registration or downloads.

What Is Volume?

Volume measures the space inside a 3D object. Every shape has a different volume formula, and using the right volume equation is critical for accurate results.

If you want to calculate volume, you must know:

The shape
The correct formula
The required dimensions

Cylinder Volume

The volume of a cylinder is one of the most searched formulas.

People often search:

volume of cylinder
cylinder volume
cylinder volume formula
volume of a cylinder formula
how to find the volume of a cylinder
calculation volume of cylinder

Cube Volume Formula:

$a^3$

Where $a$ is the side length

Cone Volume

The volume of a cone requires radius and height.

People search:

volume of cone
cone volume
cone volume formula
volume of a cone calculator
volume of conical shape

Cone Volume Formula:

$V=1/3πr^2 h$

Use a volume of a cone calculator for fast results.

Rectangular Shapes & Tanks

Many users confuse the volume of a rectangle with area. A rectangle alone is 2D, but when extended into 3D, you calculate volume.

Rectangular Volume Formula:

This formula is also used in a rectangular tank volume calculator.

Tubes & Cylindrical Pipes

To calculate hollow objects, you use a tube volume calculator.

This is useful in engineering, plumbing, and industrial design.
