# Volume Calculator

Use this volume calculator to easily calculate the volume of common bodies like a cube, rectangular box, cylinder, sphere, cone, and triangular prism. Formulas and explanation below.

## How to calculate the volume of a body?

Depending on the particular body, there is a different formula and different required information you need to calculate its volume. Below are volume formulas for the most common types of geometric bodies - all of which are supported by our online volume calculator above. All measures need to be in the same unit. The result is always in cubic units: cubic centimeters, cubic inches, cubic meters, cubic feet, cubic yards, etc.

Volume calculations are useful in a lot of sciences, in construction work and planning, in cargo shipping, in climate control (e.g. air conditioning calculations), swimming pool management, and more.

## Volume of a cube

The volume formula for a cube is *side ^{3}*, as seen in the figure below:

The only required information is the side, then you take its cube and you have the cube's volume. In this case you barely need a calculator to do the math.

Volume of a box

The volume formula for a rectangular box is *height x width x length*, as seen in the figure below:

To calculate the volume of a box or rectangular tank you need three dimensions: width, length, and height. They are usually easy to measure due to the regularity of the shape. To calculate the volume of a tank of a different shape, use our volume of a tank calculator

## Volume of a cylinder

The volume formula for a cylinder is *height x π x (diameter / 2) ^{2}*, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is

*height x π x radius*. Visual in the figure below:

^{2}You need two measurements: the height of the cylinder and the diameter of its base. In many school formulas the radius is given instead, but in real-world situations it is much easier to measure the diameter instead of trying to pinpoint the midpoint of the circular base so you can measure the radius. Our volume calculator requires that you insert the diameter of the base.

## Volume of a sphere

The volume formula for a sphere is *4/3 x π x (diameter / 2) ^{3}*, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is

*4/3 x π x radius*. Visual on the figure below:

^{3}Same as a circle, you only need one measurement of the sphere: its diameter or its radius.

## Volume of a cone

The volume formula for a cone is *(height x π x (diameter / 2) ^{2}) / 3*, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is

*(height x π x radius*, as seen in the figure below:

^{2}) / 3Despite being a somewhat complex shape, you only need to know three dimensions to calculate the volume of a regular cone. For irregular cones, which are not supported by our calculator, yet, you would also need to know the angle of the cone.

## Volume of a triangular prism

The volume formula for a triangular prism is *(height x base x length) / 2*, as seen in the figure below:

Similar to rectangular boxes, you need just three dimensions: height, base, and length.

If you are faced with a construction project, home decoration DIY job, or certain engineering tasks, the volume calculator will help you if the figure you want to calculate the volume for falls within any of the above forms. Complex figures can usually be decomposed, at least approximately, to a sum of the above basic figures.
