In the diagram not drawn to scale, Container U and Container V each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container U measures 60 cm by 85 cm by 120 cm. Container V measures 15 cm by 10 cm by 100 cm. Container W is 80 cm by 20 cm by 80 cm. Both holes are located at a height of 5 cm from the top of their respective containers. When Container U is completely filled with water and both buttons are pressed, what will be the final water level in Container W? Express your answer in mixed number.
Volume of Container U to pour into Container V
= 60 x 85 x 5
= 25500 cm³

Volume of the Container V that can be filled before overflow
= 15 x 10 x (100 - 5)
= 14250 cm³ 

Volume of water in the Container W
= 25500 - 14250
= 11250 cm³ 

Base Area of the Container W
= 80 x 20
= 1600 cm² 

Final height of the container W
= 7⁵⁰₁₆₀₀
= 7¹₃₂ cm

Answer(s): 7¹₃₂ cm
