When water freezes, the volume of ice increases (1/11) compared to that of water. Melt a piece of ice with a length of 8 decimeters, a width of 5 decimeters and a thickness of 1.2 decimeters in a cylindrical water storage bucket with a bottom surface of 8 decimeters square. The ratio of the height of the water in the bucket to the height of the bucket is 4:5. Find The height of the cylindrical storage tank.
水结成冰时，冰的体积比水增加(1/11)．把一块长8分米，宽5分米，厚1.2分米的冰熔化在一只底面为8平方分米的圆柱形储水桶里，桶里水高与桶高的比为4：5，求圆柱形储水桶的高．
