In the diagram not drawn to scale, Container R and Container S each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container R measures 70 cm by 35 cm by 110 cm. Container S measures 15 cm by 40 cm by 70 cm. Container T is 100 cm by 10 cm by 80 cm. Both holes are located at a height of 20 cm from the top of their respective containers. When Container R is completely filled with water and both buttons are pressed, what will be the final water level in Container T? Express your answer in mixed number.
Volume of Container R to pour into Container S
= 70 x 35 x 20
= 49000 cm³

Volume of the Container S that can be filled before overflow
= 15 x 40 x (70 - 20)
= 30000 cm³ 

Volume of water in the Container T
= 49000 - 30000
= 19000 cm³ 

Base Area of the Container T
= 100 x 10
= 1000 cm² 

Final height of the container T
= 19
= 19 cm

Answer(s): 19 cm
