In the diagram not drawn to scale, Container L and Container M each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container L measures 50 cm by 85 cm by 90 cm. Container M measures 35 cm by 40 cm by 60 cm. Container N is 80 cm by 60 cm by 30 cm. Both holes are located at a height of 15 cm from the top of their respective containers. When Container L is completely filled with water and both buttons are pressed, what will be the final water level in Container N? Express your answer in mixed number.
Volume of Container L to pour into Container M
= 50 x 85 x 15
= 63750 cm³

Volume of the Container M that can be filled before overflow
= 35 x 40 x (60 - 15)
= 63000 cm³ 

Volume of water in the Container N
= 63750 - 63000
= 750 cm³ 

Base Area of the Container N
= 80 x 60
= 4800 cm² 

Final height of the container N
= ⁷⁵⁰₄₈₀₀
= ⁵₃₂ cm

Answer(s): ⁵₃₂ cm
