Pyramid, a three-dimensional object with triangles as faces and a polygon base. The faces are the flat surfaces or sides, and the base is the face at the bottom. A perfect real-world example of a pyramids are the pyramids of Egypt., Prism, three-dimensional object with two polygon bases that are of the same shape and size. The faces are rectangles. An example of a prism in the real-world is a cardboard box, Cylinder, three-dimensional solid. It is one of the most basic curvilinear geometric shapes. It is the idealized version of a solid physical tin can having lids on top and bottom., cone, a three-dimensional geometric shape that tapers smoothly from a flat, circular base to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that does not contain the apex., sphere, a three- dimensional shape that looks like a ball with every point on its surface equidistant from its center..
