In the diagram not drawn to scale, Container C and Container D each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container C measures 100 cm by 45 cm by 140 cm. Container D measures 85 cm by 10 cm by 50 cm. Container E is 60 cm by 50 cm by 40 cm. Both holes are located at a height of 15 cm from the top of their respective containers. When Container C is completely filled with water and both buttons are pressed, what will be the final water level in Container E? Express your answer in mixed number.
Volume of Container C to pour into Container D
= 100 x 45 x 15
= 67500 cm³

Volume of the Container D that can be filled before overflow
= 85 x 10 x (50 - 15)
= 29750 cm³ 

Volume of water in the Container E
= 67500 - 29750
= 37750 cm³ 

Base Area of the Container E
= 60 x 50
= 3000 cm² 

Final height of the container E
= 12¹⁷⁵⁰₃₀₀₀
= 12⁷₁₂ cm

Answer(s): 12⁷₁₂ cm
