We study solutions of the 3-Dimensional wave equation with boundary Conditions on Cartesian co-ordinates, and we also study the analogous problem on a certain axis. This gives an alternative method of obtaining solutions of a corresponding problem in 3-Dimensional wave equation further, In this paper, we find the solution of 3-D wave equation .Three dimensional wave occur in earth quake, tsunami and many physical states. In this paper we discussed the 3-D wave equation in XYZ axis and using partial differential equation.

3-D wave equation Partial differential Equation Fourier series.
