Use this volume calculator to find the volume of common 3D shapes such as cubes, rectangular prisms, cylinders, cones, and spheres. Select a shape, enter the required dimensions, and get the volume instantly along with the formula used

What Is Volume?

Volume measures the amount of space inside a three-dimensional object. It tells you how much material, liquid, or air a container or solid can hold.

Volume is commonly measured in cubic units such as:

• cubic inches (in³)
• cubic feet (ft³)
• cubic meters (m³)
• liters or gallons (for liquids)

Basic Volume Formulas

Rectangular Prism (Box)

V = length × width × height

Cube

V = s³

Cylinder

V = πr²h

Sphere

V = (4/3)πr³

Cone

V = (1/3)πr²h

Each formula calculates the space occupied by the shape based on its dimensions.

Example: Finding Volume

A box with:

Length = 10
Width = 5
Height = 4

Volume = 10 × 5 × 4 = 200 cubic units

When Volume Is Used

Volume calculations are used in:

• Construction and material estimates
• Shipping and packaging
• Tank and container capacity
• Engineering and manufacturing
• Science and chemistry measurements

Tips for Accurate Volume Calculations

• Make sure all measurements use the same unit
• Convert units before calculating if necessary
• Remember that volume always uses cubic units

Frequently Asked Questions

Why is volume measured in cubic units?

Because volume measures three dimensions (length × width × height), the unit is multiplied three times.

What if my measurements are in different units?

Convert them to the same unit before calculating.

Is capacity the same as volume?

Capacity refers to how much a container can hold, which is essentially the container’s volume.
