In the diagram not drawn to scale, Container Q and Container R each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container Q measures 50 cm by 85 cm by 130 cm. Container R measures 55 cm by 10 cm by 50 cm. Container S is 70 cm by 40 cm by 40 cm. Both holes are located at a height of 20 cm from the top of their respective containers. When Container Q is completely filled with water and both buttons are pressed, what will be the final water level in Container S? Express your answer in mixed number.
Volume of Container Q to pour into Container R
= 50 x 85 x 20
= 85000 cm³

Volume of the Container R that can be filled before overflow
= 55 x 10 x (50 - 20)
= 16500 cm³ 

Volume of water in the Container S
= 85000 - 16500
= 68500 cm³ 

Base Area of the Container S
= 70 x 40
= 2800 cm² 

Final height of the container S
= 24¹³⁰⁰₂₈₀₀
= 24¹³₂₈ cm

Answer(s): 24¹³₂₈ cm
