The ratio of the bottom areas of two cylindrical containers, A and B, is 4:3. Originally, there was some water in each of the two containers. Now the same amount of water is put into the two containers. As a result, the water level in container A rises by 12 cm. How many centimeters does the water level in container B rise?
