In a cuboid tank with a length of 15 decimeters, a width of 12 decimeters, and a height of 14 decimeters, there is water 10 decimeters deep. If a cube of iron with a side length of 30 cm is sunk in water, the water will not overflow. So how many decimeters is the water depth in the tank at this time?
