Answer 2

The odd one out is Cube.

• A tetrahedron is a 3-dimensional structure consisting of 4 triangular faces and is a type of polyhedron.
• An octahedron is a 3-dimensional structure consisting of 8 triangular faces and is a type of polyhedron.
• A square pyramid is a 3-dimensional structure consisting of 3 triangular faces and 1 square base and is a type of polyhedron.
• A cube is a 3-dimensional structure consisting of 6 square faces.
• Hence, the cube is not a polyhedron, so is an odd one out among tetrahedrons, octahedrons, square pyramids, cubes​.
