What shapes does the Volume Calculator support?

Box, cube, sphere, cylinder, cone, and a rectangular-base pyramid. Select the shape from the toggle at the top and only the dimensions that shape needs are shown.

What formula does the Volume Calculator use for a sphere?

It uses the standard sphere volume formula, (4/3) × π × r³, where r is the radius you enter. A radius of 3 gives a volume of about 113.10 cubic units.

How does the Volume Calculator handle a cylinder or cone?

A cylinder's volume is π × r² × h; a cone is one-third of that, (1/3) × π × r² × h. Enter the radius and height for either shape to get the result.

Can the Volume Calculator work in any unit of measurement?

Yes. Enter every dimension in the same unit — inches, centimeters, meters, or anything else — and the reported volume is in that unit cubed.

Does the Volume Calculator upload my measurements anywhere?

No. All calculations happen locally in your browser using standard geometry formulas. Nothing you enter is sent to a server or stored by ArrayKit.

Why does the pyramid option only ask for length, width, and height?

The Volume Calculator's pyramid mode assumes a rectangular base, so volume is (1/3) × length × width × height. For a square base, enter the same value for length and width.

About Volume Calculator

Volume Calculator finds the volume of six common 3D shapes — box, cube, sphere, cylinder, cone, and rectangular-base pyramid — from the dimensions you enter. Pick a shape, fill in its length, width, height, radius, or side, and the result updates instantly using the exact geometric formula for that solid, such as (4/3)πr³ for a sphere or πr²h for a cylinder. It is handy for homework, packaging and shipping estimates, tank or container capacity, 3D-printing material estimates, or any project where you need a quick, accurate volume without doing the algebra by hand. Enter every dimension in the same unit — inches, centimeters, meters — and the result comes back in that unit cubed. Everything computes locally in your browser, so your measurements are never uploaded anywhere.

Example

Input

sphere r=3

Output

Volume: 113.10

(4/3) × π × 3³ ≈ 113.10 cubic units.

Common errors & troubleshooting

Volume looks wildly wrong for a cylinder or cone. — Check that you entered the radius, not the diameter — a common mix-up that inflates the volume by roughly 4x for cylinders and cones.
Mixing units, e.g. length in inches and height in centimeters. — Convert every dimension to the same unit before entering it. The Volume Calculator does not convert units for you.
Pyramid result seems off compared to a source that used a different base shape. — This calculator assumes a rectangular base (length × width). A square-base pyramid is just the case where length equals width.
Banner shows an error even though a number was typed. — Make sure the value is zero or positive — negative dimensions and non-numeric text are rejected.
