👉 A parallelepiped is a three-dimensional shape that has four faces, each of which are rectangles. These rectangles are perpendicular to each other and have opposite sides parallel. The edges between the rectangles are usually straight lines, but they can be curved or even hollowed out if necessary. Parallelepipedous shapes are often used in construction or architecture, especially when dealing with large volumes of material. They are also useful for storing items such as furniture or building materials.
