# Cuboid

A cuboid is a solid that has six rectangular faces--think of a typical box. All faces are either parallel or perpendicular to each other. Further, a cuboid is a right rectangular prism. A cuboid with six square faces is a cube, whereas a cuboid with at least two square faces is known as a square cuboid.

## Finding Area and Volume of a Cuboid

If a given cuboid has dimensions $a \times b \times c$, then its volume is $a\cdot b \cdot c$, and its surface area is $2ab + 2bc + 2ac$

## Finding the space diagonal of a cuboid

The space diagonal of a cuboid, $d$, is found by the formula $d^2=a^2+b^2+c^2$, where $a$,$b$ and $c$ are the side lengths of the solid
