Question

Which of the following is not a property common to a cube and a cuboid?

Answer 1

A cube and a cuboid are both 3D solids with 6 faces, 8 vertices, and 12 edges.

While a face of a cuboid may either be a square or a rectangle, every face of a cube is always a square. Thus, a cube has 6 identical faces, whereas a cuboid need not have 6 identical faces in general. However, the opposite faces of a cuboid are always identical.

Thus, of the given options, the property that is not common to a cube and a cuboid is:
6 identical faces
