In the diagram not drawn to scale, Tank H and Tank J each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Tank H measures 140 cm by 45 cm by 127 cm. Tank J measures 54 cm by 30 cm by 67 cm. Tank K is 60 cm by 30 cm by 28 cm. Both holes are located at a height of 14 cm from the top of their respective containers. When Tank H is completely filled with water and both buttons are pressed, what will be the final water level in Tank K?
Volume of Tank H to pour into Tank J
= 140 x 45 x 14
= 88200 cm³

Volume of the Tank J that can be filled before overflow
= 54 x 30 x (67 - 14)
= 85860 cm³ 

Volume of water in Tank K
= 88200 - 85860
= 2340 cm³ 

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

Final height of Tank K
= 2340 ÷ 1800
= 1.3 cm

Answer(s): 1.3 cm
