There are two equal-height containers in the laboratory. The radius of the conical container is 3 cm, and the radius of the cylindrical container is 2 cm. If the conical container is filled with water and poured into the cylindrical container, the water depth is greater than the height of the container. (8/9) is 5 centimeters lower, so what is the height of the two containers in centimeters?
实验室里有两个等高的容器，圆锥形容器的半径为3厘米，圆柱形容器的半径是2厘米，如果圆锥形容器装满水倒入圆柱形容器内，这时水深比容器高度的(8/9)低5厘米，那么这两个容器的高都是多少厘米．
