In the diagram not drawn to scale, Container J and Container K each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container J measures 100 cm by 65 cm by 80 cm. Container K measures 35 cm by 50 cm by 70 cm. Container L is 70 cm by 70 cm by 40 cm. Both holes are located at a height of 20 cm from the top of their respective containers. When Container J is completely filled with water and both buttons are pressed, what will be the final water level in Container L? Express your answer in mixed number.
Volume of Container J to pour into Container K
= 100 x 65 x 20
= 130000 cm³

Volume of the Container K that can be filled before overflow
= 35 x 50 x (70 - 20)
= 87500 cm³ 

Volume of water in the Container L
= 130000 - 87500
= 42500 cm³ 

Base Area of the Container L
= 70 x 70
= 4900 cm² 

Final height of the container L
= 8³³⁰⁰₄₉₀₀
= 8³³₄₉ cm

Answer(s): 8³³₄₉ cm
