How It Works

1

Select Shape

Choose from cube, rectangular prism, cylinder, sphere, cone, pyramid, or triangular prism.

2

Enter Dimensions

Input the required measurements. Different shapes need different dimensions (length, width, height, radius).

3

Choose Units

Select your unit of measurement - metric (mm, cm, m) or imperial (inches, feet).

4

Get Volume

Click calculate to get the volume in cubic units with the formula used shown.

Pro Tips for Volume Calculations

Measure Carefully

Small measurement errors get magnified when cubed. Double-check your measurements for accurate volume calculations.

Consistent Units

Make sure all dimensions are in the same unit before calculating. Mixing cm and inches will give wrong results.

Break Down Complex Shapes

For irregular objects, divide them into simple shapes, calculate each volume separately, then add them together.

Remember Key Formulas

Cube = s³, Sphere = (4/3)πr³, Cylinder = πr²h, Cone = (1/3)πr²h. These cover most practical needs.

Frequently Asked Questions

Volume is the amount of 3D space occupied by an object. It's measured in cubic units like cubic centimeters (cm³), cubic meters (m³), or cubic feet (ft³).
Volume = side³ (side × side × side). If a cube has 5cm sides, volume = 5³ = 125 cubic centimeters.
Volume = π × radius² × height. For a cylinder with radius 3cm and height 10cm: V = 3.14159 × 9 × 10 = 282.74 cm³.
Volume = (4/3) × π × radius³. For a sphere with radius 5cm: V = (4/3) × 3.14159 × 125 = 523.6 cm³.
Volume = (1/3) × π × radius² × height. A cone is exactly 1/3 the volume of a cylinder with the same base and height.
You need length, width, and height. Volume = length × width × height. This is the formula for any box shape.
1 m³ = 1,000,000 cm³. 1 ft³ = 1,728 in³. 1 m³ ≈ 35.31 ft³. Our calculator handles these conversions automatically.
Volume is the space an object occupies. Capacity is how much a container can hold. They're often used interchangeably but technically different.
For irregular shapes, you'd need to break them into regular shapes, calculate each volume, then add them together. Or use water displacement for physical objects.
Pi (3.14159...) appears in formulas for shapes with circular cross-sections - spheres, cylinders, cones. It relates the circumference to the diameter of circles.
