In the diagram not drawn to scale, Container D and Container E each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container D measures 90 cm by 65 cm by 80 cm. Container E measures 35 cm by 30 cm by 100 cm. Container F is 90 cm by 30 cm by 50 cm. Both holes are located at a height of 20 cm from the top of their respective containers. When Container D is completely filled with water and both buttons are pressed, what will be the final water level in Container F? Express your answer in mixed number.
Volume of Container D to pour into Container E
= 90 x 65 x 20
= 117000 cm³

Volume of the Container E that can be filled before overflow
= 35 x 30 x (100 - 20)
= 84000 cm³ 

Volume of water in the Container F
= 117000 - 84000
= 33000 cm³ 

Base Area of the Container F
= 90 x 30
= 2700 cm² 

Final height of the container F
= 12⁶⁰⁰₂₇₀₀
= 12²₉ cm

Answer(s): 12²₉ cm
