As shown in the figure, three cylinders A, B, and C were stood right in the water tank and water was put in until the height of the water surface was set to 18 cm.
When A and B were taken out of the tank, the height of the water surface was 5 cm.
When A and C were taken out, the height of the water surface was 9 cm.
When B and C were taken out, the height of the water surface was 6 cm.
Answer the following questions.
(1) Find the ratio of the base area of the cylinders A, B, and C by the ratio of the least integer.
(2) Find the height of the water surface when only A is taken out.
