In the diagram not drawn to scale, Container Z and Container A each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container Z measures 60 cm by 65 cm by 110 cm. Container A measures 25 cm by 30 cm by 90 cm. Container B is 100 cm by 10 cm by 70 cm. Both holes are located at a height of 15 cm from the top of their respective containers. When Container Z is completely filled with water and both buttons are pressed, what will be the final water level in Container B? Express your answer in mixed number.
Volume of Container Z to pour into Container A
= 60 x 65 x 15
= 58500 cm³

Volume of the Container A that can be filled before overflow
= 25 x 30 x (90 - 15)
= 56250 cm³ 

Volume of water in the Container B
= 58500 - 56250
= 2250 cm³ 

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

Final height of the container B
= 2²⁵⁰₁₀₀₀
= 2¹₄ cm

Answer(s): 2¹₄ cm
