In the diagram not drawn to scale, Tank A and Tank B each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Tank A measures 132 cm by 57 cm by 121 cm. Tank B measures 57 cm by 24 cm by 56 cm. Tank C is 60 cm by 30 cm by 20 cm. Both holes are located at a height of 12 cm from the top of their respective containers. When Tank A is completely filled with water and both buttons are pressed, what will be the final water level in Tank C?
Volume of Tank A to pour into Tank B
= 132 x 57 x 12
= 90288 cm³

Volume of the Tank B that can be filled before overflow
= 57 x 24 x (56 - 12)
= 60192 cm³ 

Volume of water in Tank C
= 90288 - 60192
= 30096 cm³ 

Base area of Tank C
= 60 x 30
= 1800 cm² 

Final height of Tank C
= 30096 ÷ 1800
= 16.72 cm

Answer(s): 16.72 cm
