# Cuboid

## Definition Of Cuboid

Cuboid is a polyhedron with six rectangular plane faces.

There are 12 edges and 8 vertices in a cuboid.
Cuboid is also called as right rectangular prism or rectangular parallelepiped box.
If all the edges of a cuboid are equal then it forms a cube.
In a cuboid opposite faces are equal and parallel and all angles are right angles.

Formulas for the above rectangular box:
Volume = lwh
Lateral Surface Area = 2lh + 2wh
Surface Area = 2lw + 2lh + 2wh
