Cube vs Cuboid

Last Updated : 22 Aug, 2026

Three-dimensional (3D) shapes are solid objects that have length, breadth, and height. Unlike two-dimensional shapes, they occupy space and have volume.

A cube and a cuboid are both three-dimensional (3D) shapes made up of flat rectangular faces.

Cube---Cuboid
Basic structure of a cube and cuboid
  • Cube: A three-dimensional solid in which all six faces are equal squares. A cube consists of 6 faces, 12 edges, 8 vertices, 12 face diagonals, and 4 space diagonals.
  • Cuboid: A three-dimensional shape with 6 rectangular faces. Opposite faces are equal. A cuboid consists of 6 faces, 12 edges, 8 vertices, 12 face diagonals, and 4 space diagonals.

The main difference between cube and cuboid is tabulated below:
