Cuboid Volume Calculator
Calculate the volume of a cuboid (rectangular prism) from its length, width, and height.
Formula
V = l × w × h
- Volume = length × width × height (l × w × h).
- All dimensions must be positive.
Cuboid Volume Example
Inputs
- Length: 5
- Width: 4
- Height: 3
Cuboid with length 5, width 4, height 3 has volume V = 5 × 4 × 3 = 60 units³.
Frequently asked questions
What is a cuboid?
A cuboid is a 3D shape with 6 rectangular faces, 12 edges, and 8 vertices.
How is volume calculated?
Volume = length × width × height (l × w × h).
When would I use this?
For container capacity, room volume, shipping box sizing, or estimating storage space.
What's a cube?
A cube is a special cuboid where l = w = h.
How can I verify the calculation manually?
Use the displayed formula and work through the numbers step by step. If your manual result differs slightly, check rounding and unit conversions first.
Can I use this for planning and budgeting?
Yes. Run best-case, expected, and worst-case inputs to compare outcomes and make safer planning decisions.
