1) A rectangular parallelepiped is a polyhedron with six faces, each of which is generally a rectangle. The opposite faces of the box are equal.
2) The sum of the lengths of all edges of a rectangular parallelepiped is found as: L = 4 (a + b + c).
3) We get: L = 4 (a + b + c) = 4 (13 + 16 + 21) = 4 * 50 = 200
Answer: 200
