The solid shape with 6 rectangular faces where not all sides are identical is called a rectangular prism, also known as a cuboid. It has opposite faces that are equal in size, but the lengths of the edges can vary, resulting in different dimensions for each face. This shape is commonly found in everyday objects, such as boxes and bricks.

A rectangular prism is a hexahedron with some rectangular sides. There is no requirement that all sides be rectangles. If they are, the solid is a right rectangular prism, or cuboid.
