Volume Calculator
Use clear formulas for five common three-dimensional solids.
Volume Calculator
Find the volume of five common solids using consistent linear measurements.
Cylinder volume
50.2654825 cm³
All dimensions are treated as the selected unit; the result is in that unit cubed.
Use one consistent unit for every dimension. This calculator does not estimate material waste, fill level, or construction quantities.

What This Calculator Does
Find the geometric volume of a cube, rectangular prism, sphere, cylinder, or cone. Enter dimensions in one selected linear unit; the answer is expressed in that unit cubed.
How It Works
Choose a solid and enter its required dimensions. The calculator applies the corresponding geometric formula: for example, a cylinder uses V = πr²h and a cone uses one-third of that cylinder volume. It does not estimate material quantities or account for waste.
Example
A cylinder with radius 2 cm and height 5 cm has volume π × 2² × 5 = 20π ≈ 62.83 cm³. The displayed unit is cubic centimetres because the input dimensions are in centimetres.
Formula
V = s³V = lwhV = 4πr³ / 3V = πr²hV = πr²h / 3Reading the Results
Volume
The three-dimensional space inside the selected ideal geometric solid, expressed in cubic units.
Frequently Asked Questions
What is the difference between volume and surface area?
Volume measures the three-dimensional space inside a solid and uses cubic units. Surface area measures the total area of its outside faces or curved surface and uses square units.
Can I mix centimetres and metres for dimensions?
No. Convert every dimension to the same linear unit first. The result is displayed in the selected unit cubed.
Does this estimate gravel, concrete, or material needed?
No. It calculates ideal geometric volume only. Construction estimates may require shape-specific adjustments, depth, compaction, waste, and product coverage.
