👉 In geometry, a parallelepiped is defined as a three-dimensional geometric shape that has all its edges parallel to each other and all sides meeting at right angles. It can also be defined as a solid with six rectangular faces and four triangular faces, where opposite edges are parallel and the opposite corners (or vertices) of opposite faces are adjacent. Parallelepipedinals are commonly used in various fields such as architecture, engineering, physics, and computer graphics. They have many applications in science and technology
