cuboid – a 3D shape with all the sides made of rectangles

(pronounced kyoo-boyd)

To remember the meaning of cuboid, use the following mnemonic:

The cube was annoyed (cuboid) after being stretched. Now all its sides are rectangles.

A cuboid is a three-dimensional geometric shape that has six rectangular faces, twelve edges, and eight corners (vertices). It's essentially a box shape where opposite faces are identical rectangles and parallel to each other.

Common examples of cuboids include bricks, shoeboxes and most rooms in buildings.
