There are two water tanks, A and B. Measured from the inside, the length of A water tank is 12dm, the width is 8dm, and the height is 5dm. The length of B water tank is 8dm, the width is 8dm, and the height is 6dm. Tank A is full of water and Tank B is empty. Pour some of the water in tank A into tank B so that the water levels in both tanks are the same. How many decimeters are the water levels in the two tanks now?
有甲、乙两个水箱，从里面测量，甲水箱长12dm、宽8dm、高5dm，乙水箱长8dm，宽8dm，高6dm．甲水箱装满水，乙水箱空着．现将甲水箱里的一部分水倒入乙水箱中，使两水箱的水面高度一样．现在两个水箱的水面高多少分米？
