Answer 2

Volume of the each metallic box= 60*40*30cm³
                                                    =72000cm³
So,
the volume of the new box so formed=2*72000cm³
                                                             =144000cm³
Therefore,
the height of the new box={144000/(115*60)}cm³
                                        =144000/6900cm³
                                         =20.869cm³
                                          =21cm³(approx)
