There is a wooden cube with an edge length of 1 meter. It is known that if it is placed in water, 0.7 meters will be immersed in the water. Now divide it into small cubes with a side length of 0.2 meters, and put all the small cubes into the water. What is the sum of the surface areas of each small cube directly in contact with the water?
有一个棱长为1米的木质正方体，已知将其放入水中将有0.7米浸入水里．现将其分割成棱长为0.2米的小正方体，并将所有的小正方体都放入水中，求此时各小正方体直接和水接触的表面积的和是多少？
