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 136 cm by 44 cm by 126 cm. Tank B measures 56 cm by 20 cm by 70 cm. Tank C is 70 cm by 20 cm by 30 cm. Both holes are located at a height of 14 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
= 136 x 44 x 14
= 83776 cm³

Volume of the Tank B that can be filled before overflow
= 56 x 20 x (70 - 14)
= 62720 cm³ 

Volume of water in Tank C
= 83776 - 62720
= 21056 cm³ 

Base area of Tank C
= 70 x 20
= 1400 cm² 

Final height of Tank C
= 21056 ÷ 1400
= 15.04 cm

Answer(s): 15.04 cm
