In the diagram not drawn to scale, Container Y and Container Z each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container Y measures 90 cm by 75 cm by 130 cm. Container Z measures 65 cm by 10 cm by 70 cm. Container A is 90 cm by 40 cm by 20 cm. Both holes are located at a height of 15 cm from the top of their respective containers. When Container Y is completely filled with water and both buttons are pressed, what will be the final water level in Container A? Express your answer in mixed number.
Volume of Container Y to pour into Container Z
= 90 x 75 x 15
= 101250 cm³

Volume of the Container Z that can be filled before overflow
= 65 x 10 x (70 - 15)
= 35750 cm³ 

Volume of water in the Container A
= 101250 - 35750
= 65500 cm³ 

Base Area of the Container A
= 90 x 40
= 3600 cm² 

Final height of the container A
= 18⁷⁰⁰₃₆₀₀
= 18⁷₃₆ cm

Answer(s): 18⁷₃₆ cm
