We live in a three-dimensional world, which means everything takes up space. Volume is the measure of exactly how much space a 3D object occupies. Whether you are filling a swimming pool with water or packing a lunch box, you are dealing with volume. Our Volume of 3D Shapes Calculator helps you quantify this space using simple measurements.

The Big Three Shapes

• Cube: A perfect box where every side (length, width, height) is the same. Think of a dice or a sugar cube.
• Rectangular Prism: A box where the sides can be different lengths. Examples include cereal boxes, bricks, and books.
• Cylinder: A shape with circular ends and straight sides. Common examples are soda cans, batteries, and pipes.

How do we calculate it? The general rule for most simple 3D shapes is Area of Base × Height.
For a Prism, you multiply Length × Width (base area) × Height.
For a Cylinder, you multiply $\pi \times r^2$ (circle area) × Height.
Using this Volume of 3D Shapes Calculator saves you from doing the messy multiplication, especially when Pi ($\pi$) is involved!

Why is this useful? Understanding volume is critical for many jobs. Engineers need it to design tanks and engines. Architects use it to calculate heating and cooling needs for buildings. Even chefs use it when measuring ingredients! This Volume of 3D Shapes Calculator is a great way to check your homework or estimate real-world capacities.
