Given an Euler brick with edges (a, b, c), the triple (bc, ac, ab) constitutes an Euler brick as well. Perfect cuboid Template:Unsolved A perfect cuboid (also called a perfect box) is an Euler brick whose body diagonal is also an integer.
About Project Euler. Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.
