Question

State true or false:

Cube is a regular polyhedron where cuboid is not.

• A. True
• B. False

Answer 1

The correct option is A True

We know that, a polyhedron is a 3D shape that has flat surfaces. Hence, a regular polyhedron is a polyhedron having regular flat surfaces or congruent flat surfaces.

In a cube, all the surfaces are flat and squares which are all congruent.

Hence, a cube is a regular polyhedron.

However, in a cuboid, we have rectangular flat surfaces which are not congruent.

Hence, a cuboid is not a regular polyhedron.

Hence, the given statement is true.
