Free Volume Calculator Online
Volume of cube, sphere, cylinder, cone and other 3D shapes
The Volume Calculator computes the volume of common 3D geometric shapes including cubes, rectangular prisms, spheres, cylinders, cones, and pyramids. It uses the precise formula for each shape and accepts any unit of measurement. Engineers, architects, students, and hobbyists use it to calculate how much material fits inside a container or how much space an object occupies.
Frequently Asked Questions
About the Volume Calculator
Volume is the three-dimensional measure of how much space an object occupies. Different shapes require completely different formulas: cubes (V = s³), rectangular prisms (V = l×w×h), spheres (V = 4/3·πr³), cylinders (V = πr²h), cones (V = 1/3·πr²h), and pyramids (V = 1/3·base area×h).
This calculator accepts dimensions in any unit — millimeters, centimeters, meters, inches, or feet — and converts results accordingly. It covers the most common shapes encountered in geometry courses and real-world applications.
Practical uses include calculating concrete volume needed for a foundation, determining tank capacity for liquid storage, figuring out how many cubic meters of soil a garden bed holds, and solving geometry exam problems. Engineers also use volume in buoyancy calculations and material weight estimation (volume × density = mass).
When Should You Use This?
The Volume Calculator is ideally suited for students, teachers, engineers, and scientists who need to perform quick, accurate calculations related to general calculations. Use this tool when you need to verify figures, compare different scenarios, or get a precise answer without manual computation errors.
What Does The Result Mean?
The calculated output provides an instant, accurate resolution to your input parameters. You can use these results directly for your planning, assignments, or professional tasks, knowing they are based on standardized formulas.
Example Calculation
Volume of a cylinder with radius 4 cm and height 10 cm
📥 Inputs
- Shape: Cylinder
- Radius: 4 cm
- Height: 10 cm
🔢 Calculation Steps
- 1Formula: V = π × r² × h
- 2r² = 4² = 16 cm²
- 3π × r² = 3.14159 × 16 = 50.265 cm²
- 4V = 50.265 × 10 = 502.65 cm³
Limitations of this Calculator
