In the diagram not drawn to scale, Container M and Container N each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container M measures 80 cm by 55 cm by 140 cm. Container N measures 35 cm by 10 cm by 100 cm. Container P is 60 cm by 10 cm by 70 cm. Both holes are located at a height of 15 cm from the top of their respective containers. When Container M is completely filled with water and both buttons are pressed, what will be the final water level in Container P? Express your answer in mixed number.
Volume of Container M to pour into Container N
= 80 x 55 x 15
= 66000 cm³

Volume of the Container N that can be filled before overflow
= 35 x 10 x (100 - 15)
= 29750 cm³ 

Volume of water in the Container P
= 66000 - 29750
= 36250 cm³ 

Base Area of the Container P
= 60 x 10
= 600 cm² 

Final height of the container P
= 60²⁵⁰₆₀₀
= 60⁵₁₂ cm

Answer(s): 60⁵₁₂ cm
