What is the difference between a cuboid and a square prism?

A cuboid is a three-dimensional geometric figure with six rectangular faces, while a square prism, also known as a rectangular prism when its bases are rectangles, specifically has square bases and four rectangular lateral faces. Essentially, all square prisms are cuboids, but not all cuboids are square prisms since cuboids can have rectangular faces of different dimensions. In summary, the defining feature of a square prism is its square bases.
