Cuboid Calculator
Calculate volume, surface area, and diagonal of a cuboid.
Formula
Volume = l×w×h; SA = 2(lw+lh+wh); Diagonal = √(l²+w²+h²)
- Volume = l×w×h; SA = 2(lw+lh+wh); Diagonal = √(l²+w²+h²)

Frequently asked questions
What is a cuboid (rectangular prism)?
A cuboid is a 3D shape with 6 rectangular faces, 12 edges, and 8 vertices. Length, width, and height define its dimensions.
How is volume calculated?
Volume = length × width × height. This represents the space inside the cuboid.
How is surface area calculated?
Surface Area = 2(lw + lh + wh). This is the sum of the areas of all 6 rectangular faces.
What is the space diagonal?
The space diagonal is the longest line segment inside the cuboid, from one corner to the opposite corner. Formula: √(l² + w² + h²).
