1. Divide the cylinder into upper and lower parts. The upper part is filled with water for six minutes, the height is 30-6=24 cm, and the volume is 4 times that of the lower part divided by 6. The ratio is 4 1.4 1= 12 to 3.

2. The ratio of the upper volume to the lower water volume is 6: 1= 12: 2. That is to say, the ratio of the lower volume to the lower water volume is 3: 2, while the cuboid volume is 3-2= 1, and the ratio of the lower part of the cylinder to the cuboid volume is 3: 1. Because the height is certain, the floor area ratio is equal to the bottom area ratio. The bottom area of the container is equal to the bottom of the cuboid.

The original question is whether you have forgotten the word "bottom"

There are graphic problems that are difficult to describe. My expressive ability is limited, and I don't know if I can understand them.
