The nonconforming Wilson's brick classically is restricted to regular hexahedral meshes. Lesaint and Zlamal[6] relaxed this constraint for the two-dimensional analonue of this element. In this paper we extend their results to three dimensions and prove that and where u is the exact solution, u_h is the approximate solution and ||·|| is the usual norm for the Sobolev space H^1 (Ω).
