Xiao Yong's family has two cuboid water tanks. There is water in the first tank, and the second tank is empty. From the inside, the first tank is 40cm long, 20cm wide and15cm deep. Cylinder b is 20 cm long.
Solution: The existing water in cylinder A is 40× 20× 15 = 12000 cubic centimeters, and the bottom area of cylinder B is 20× 20 = 400. Combine the bottom areas of the two tanks into 800+400 = 1200 cm2 and 12000.
Answer: The water depth of the existing two cylinders is 10 cm.
