For a particle confined in a three-dimensional cubic box of side length (a), the wavefunction (\psi(x,y,z)) must satisfy boundary conditions imposed by the infinitely high potential walls. Inside the box, the potential energy is zero, while outside the box it is infinite. Therefore, the particle cannot exist outside the box, and the wavefunction must be zero at the boundaries. If the cubic box extends from (x=0)
