In the diagram not drawn to scale, Tank G and Tank H each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Tank G measures 132 cm by 45 cm by 142 cm. Tank H measures 53 cm by 27 cm by 70 cm. Tank J is 63 cm by 30 cm by 25 cm. Both holes are located at a height of 14 cm from the top of their respective containers. When Tank G is completely filled with water and both buttons are pressed, what will be the final water level in Tank J?
Volume of Tank G to pour into Tank H
= 132 x 45 x 14
= 83160 cm³

Volume of the Tank H that can be filled before overflow
= 53 x 27 x (70 - 14)
= 80136 cm³ 

Volume of water in Tank J
= 83160 - 80136
= 3024 cm³ 

Base area of Tank J
= 63 x 30
= 1890 cm² 

Final height of Tank J
= 3024 ÷ 1890
= 1.6 cm

Answer(s): 1.6 cm
