A cuboid tank with a length of 6dm and a width of 3dm is filled with water, and all the water in the tank is poured into a cube tank, which is just full. It is known that the edge length of the cube tank is twice the width of the cuboid tank, so what is the height of the cuboid tank in dm?
在一个长6dm、宽是3dm的长方体少水槽里盛满水，水槽中的水全部倒入一个正方体水槽中，也正好装满．已知正方体水槽的棱长是长方体水槽宽的2倍，那么长方体水槽的高是多少dm？
