19. Assertion: A cone is a polyhedron.

Question

Reason: A cube is a 3d solid object bounded by six square faces, faces or sides with three meeting at each vertex.

Answer 1

The assertion is false.

The reason is also false. A cube is a polyhedron, but a cone is not. A cone is a three-dimensional geometric shape with a circular base tapering to a point, while a cube is a polyhedron with six square faces.
