The key difference between a cube and a cuboid is: a cube has six square-shaped faces of the same size, but a cuboid has rectangular faces. Although both cubes and cuboids look the same in structure, they have a few different properties based on edge length, diagonals and faces.

A cube and a cuboid look very similar to each other in structure but both the shapes have their own properties based on edge, length, diagonals, and faces. The main difference between a cube and a cuboid is that a cube has six square-shaped faces of the same size but a cuboid has rectangular faces.

The main difference between a cube and a cuboid is that a cube has six equal sides and all the angles are 90 degrees, whereas a cuboid has six sides that are not all equal and the angles are not all 90 degrees.

The difference between the cube and cuboid shapes are as follows: The sides of the cube are equal but for cuboids they are different. The sides of the cube are square, but for the cuboids they are in rectangular shape. All the diagonals of the cube are equal but a cuboid has equal diagonals for only parallel sides.
