We know that surface area of cuboid= 2(lb+bh+lh)
                                                   1372= 2(2x*4X+2x*1x+4x*1x)
                                                   1372= 2(8x+2x+4x)
                                                 1372/2= 14x
                                                 14x= 686
                                                    x=49
