In the diagram not drawn to scale, Tank F and Tank G each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Tank F measures 134 cm by 57 cm by 149 cm. Tank G measures 59 cm by 25 cm by 70 cm. Tank H is 70 cm by 22 cm by 20 cm. Both holes are located at a height of 14 cm from the top of their respective containers. When Tank F is completely filled with water and both buttons are pressed, what will be the final water level in Tank H?
Volume of Tank F to pour into Tank G
= 134 x 57 x 14
= 106932 cm³

Volume of the Tank G that can be filled before overflow
= 59 x 25 x (70 - 14)
= 82600 cm³ 

Volume of water in Tank H
= 106932 - 82600
= 24332 cm³ 

Base area of Tank H
= 70 x 22
= 1540 cm² 

Final height of Tank H
= 24332 ÷ 1540
= 15.8 cm

Answer(s): 15.8 cm
