A prism whose bases and lateral faces are rectangles.
A rectangular prism whose faces are squares.
A prism whose bases are triangles
A three-dimensional shape with two parallel congruent circular faces whose cross sections (taken parallel to these circular faces) are circular.
A cone is like a pyramid with a circular base. (See Pyramid.)
A sphere is the set of all points in space that are a fixed distance from a common point called the center.
