In the diagram not drawn to scale, Container S and Container T each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container S measures 50 cm by 75 cm by 140 cm. Container T measures 15 cm by 20 cm by 50 cm. Container U is 100 cm by 50 cm by 50 cm. Both holes are located at a height of 5 cm from the top of their respective containers. When Container S is completely filled with water and both buttons are pressed, what will be the final water level in Container U? Express your answer in mixed number.
Volume of Container S to pour into Container T
= 50 x 75 x 5
= 18750 cm³

Volume of the Container T that can be filled before overflow
= 15 x 20 x (50 - 5)
= 13500 cm³ 

Volume of water in the Container U
= 18750 - 13500
= 5250 cm³ 

Base Area of the Container U
= 100 x 50
= 5000 cm² 

Final height of the container U
= 1²⁵⁰₅₀₀₀
= 1¹₂₀ cm

Answer(s): 1¹₂₀ cm
