EducationVolume Calculator — How it works
This calculator helps you quickly find the volume of geometric solids. You can calculate the volume of a cube, sphere, or cylinder.
Volume of a cube
If the edge length of the cube is known, use the formula:
- V = a³
Here a is the edge length of the cube.
Volume of a sphere
For a sphere, the formula is:
- V = 4/3 × π × r³
Here r is the radius of the sphere.
Volume of a cylinder
For a cylinder, use the formula:
- V = π × r² × h
Here r is the radius of the base and h is the height of the cylinder.
Example calculation
If a cylinder has radius 3 and height 10, then:
- V = π × 3² × 10 = π × 9 × 10 = 90π ≈ 282.7433
What is useful about this calculator
The calculator automatically shows the formula, intermediate steps, shape visualization, and the final result. Both whole and decimal values are supported.
Frequently Asked Questions
