No, a cuboid has 8 sides * * * * * That is not correct. A cuboid also has six faces. A cuboid is made up of three pairs of congruent rectangles - in the shape of a brick. The relationship between a cube and a cuboid is the 3-dimensional equivalent of the relationship between a square and a rectangle in 2-d.

### What the relationships between cube and cuboid?

A cuboid is a solid (3-dimensional) object with six faces that are rectangular and which meet at right angles. A cube is a special case of a cuboid, where all sides have the same length. The relationship is the same as that between a square and a rectangle - except that this is in 3-d instead of 2-d.
