The two figures have same height.The diference between them is one is cylinder and another is cube.

lateral surface area of cylinder = 2\times \pi \times r\times h

                                                  =2\times \pi \times 3.5\times 7

                                                  =154 cm^{2}

lateral surface area of cube = 4\times side^{2}

                                           =4\times 7^{2}   

                                           =4\times 49

                                          =196 cm^{2}

Cube  has a larger lateral surface area.
