A cuboid container filled with water is 16 decimeters high. Now pour some water into an empty cylindrical container so that the water depths of both containers are equal. It is known that the ratio of the bottom area of the rectangular parallelepiped container to the cylindrical container is 5:3 (measured from the inside of the container), find the current water depth in the container.
一个装满水的长方体容器高16分米，现将一部分水倒入一个空的圆柱体容器中，使两个容器的水深相等．已知长方体容器和圆柱体容器底面积的比是5：3(从容器里面量)，求现在容器中的水深．
