The Area and Volume Calculator calculates area of 2D shapes and surface area and volume of 3D shapes instantly.
| Shape | Area Formula | Volume Formula |
|---|---|---|
| Circle | π × r² | — |
| Rectangle | L × W | — |
| Triangle | ½ × B × H | — |
| Sphere | 4πr² | 4/3 × πr³ |
| Cylinder | 2πr(r+h) | πr²h |
| Cube | 6a² | a³ |
It calculates area for shapes like circles, rectangles, triangles, and squares, and volume for 3D shapes such as spheres, cubes, cylinders, and cones using standard geometry formulas.
You can enter measurements in any consistent unit (cm, m, inches, feet). The result will be in square units for area and cubic units for volume, matching whatever unit you input.
Area measures the flat surface a 2D shape covers and is expressed in square units, while volume measures the space a 3D object holds and is expressed in cubic units.
