                                            •  Its opposite faces are

                                                equal.

                   Cylinder: The figure given below is a cylinder.                Given below are some examples

                                            •  A cylinder has 3 faces             of cylinders.

                                            •  A cone has 2 faces (one  of cones.

                                                plane and the other

                                                curved).
