# Area of a parallelepiped

A parallelepiped is a three-dimensional shape with six faces bounded by three pairs of parallel planes, so all of its faces are parallelograms. Essentially, it is formed by the six sides of a parallelogram to produce a three-dimensional figure or prism that has a parallelogram base.

## Box Properties

- A box is a 3D shape.
- Has 6 faces.
- It has 12 edges and 8 vertices.
- The faces of the parallelepiped are parallelogram.
- This is a prism with a parallelogram at the base.
- Each side is opposite parallel.
- The diagonal of each face is called the face diagonal.
- The diagonal of the three-dimensional body of the box is called the diagonal of the body.
