Rectangular Prism

A rectangular prism is a three-dimensional shape with six faces that are rectangles. It has length, width, and height, with all sides meeting at right angles. Think of it as a box or a brick—like a cereal box or a shoebox. It occupies space and has volume, which is how much it can hold inside. The surface area is the total area of all its faces. Rectangular prisms are common in everyday objects and are used in mathematics to understand volume, surface area, and spatial reasoning.
