This paper illustrates that the perfect cuboid problem, which is also known as perfect Euler brick problem, can be easily and conveniently represented by a prism instead of a cuboid. This will make the concept simpler and easier to understand. It eliminates the use of solid diagonal of the cube, which used to be a hidden line. It makes the same line to be represented on the surface of the prism as face diagonal. All the seven lines representing the integer numbers are on the surfaces and on the edges. This eliminates repeated extra lines and makes the simpler visual meaning of the problem. The aim of this paper is not to prove or disprove the problem but to clearly illustrate that the key factor is common numbers in Pythagorean triplets, finally converting the whole problem into 2D with a set of triangles.
