Diagonal of a parallelepiped: $$d$$

Surface area: $$S$$
Volume: $$V$$

1. A rectangular parallelepiped is a three-dimensional figure bounded by six rectangular faces. A rectangular parallelepiped is a particular case of a prism.
1. A rectangular parallelepiped whose faces are squares is called a cube.
2. Diagonal of a rectangular parallelepiped
$$d = \sqrt {{a^2} + {b^2} + {c^2}}$$
3. Total surface area of a rectangular parallelepiped
$$S = 2\left( {ab + ac + bc} \right)$$
4. Volume of a rectangular parallelepiped
$$V = abc$$
