A cuboid is a shape that looks similar to a box and has six flat sides. Cuboids also have only right angles, and all of the faces are rectangles.
The cuboid is a rectangular prism, and can be found throughout the world, from buildings to boxes. The cuboid can also be a square prism depending on its lengths. If at least two of the cuboid's lengths are equal, then the cuboid can be called a square prism and a rectangular prism.
A cube is also a type of cuboid and is also known as a hexahedron. A cube is also a prism, but requires that each face be a square as well as that all three lengths be equal. Cubes are also platonic solids.
The volume of a cuboid can be calculated by multiplying the length of the cuboid by its width and its height. The surface area of a cuboid can be calculated by following the formula A = 2wl + 2lh + 2hw. In this formula, w = width, l = length and h = height.
The term "cuboid" comes from the word "cube" and the word ending "-oid," which means "similar to, or resembling." Thus, the name "cuboid" means that, "it is like a cube."
