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 124 cm by 58 cm by 124 cm. Tank H measures 50 cm by 22 cm by 57 cm. Tank J is 64 cm by 25 cm by 27 cm. Both holes are located at a height of 15 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
= 124 x 58 x 15
= 107880 cm³

Volume of the Tank H that can be filled before overflow
= 50 x 22 x (57 - 15)
= 46200 cm³ 

Volume of water in Tank J
= 107880 - 46200
= 61680 cm³ 

Base area of Tank J
= 64 x 25
= 1600 cm² 

Final height of Tank J
= 61680 ÷ 1600
= 38.55 cm

Answer(s): 38.55 cm
