# Parallelepiped

A parallelepiped is a solid formed by six parallelograms. A box is a typically example of a parallelepiped.

A rectangular parallelepiped, where all angles are 90˚, is also called a rectangular cuboid or sometimes just a cuboid.

## The surface area of a cuboid

The surface area of a rectangular parallelepiped is given by the following formula:

where A is the surface area and a, b and c is height, width and depth.

## Volume of a cuboid

The volume of a rectangular parallelepiped is given by:

where V is the volume and a, b and c is height, width and depth.

## Volume of an oblique parallelepiped

The volume of an oblique parallelepiped (nonrectangular parallelepiped) is given by:

where V is the volume. a, b and c is height, width and depth. θ is one of the oblique angles (the acute or the obtuse angle).
