| Abstract: | Through operating, probing and discussing, we solved the problem about exterior area decrease in putting and meeting square body and cuboids body, ranging to the pertinent problem of exterior area increase in comminuting polyhedron distinguishingly putting and meeting graphics in which exterior area was out of change. Let the students put and meet freely and radiated imagination, thus inspiring students interest of explorative study. |
