In the diagram not drawn to scale, Container H and Container J each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container H measures 90 cm by 85 cm by 140 cm. Container J measures 75 cm by 10 cm by 90 cm. Container K is 50 cm by 60 cm by 40 cm. Both holes are located at a height of 15 cm from the top of their respective containers. When Container H is completely filled with water and both buttons are pressed, what will be the final water level in Container K? Express your answer in mixed number.
Volume of Container H to pour into Container J
= 90 x 85 x 15
= 114750 cm³

Volume of the Container J that can be filled before overflow
= 75 x 10 x (90 - 15)
= 56250 cm³ 

Volume of water in the Container K
= 114750 - 56250
= 58500 cm³ 

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

Final height of the container K
= 19¹⁵⁰⁰₃₀₀₀
= 19¹₂ cm

Answer(s): 19¹₂ cm
