In the diagram not drawn to scale, Tank M and Tank N each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Tank M measures 136 cm by 55 cm by 131 cm. Tank N measures 55 cm by 24 cm by 69 cm. Tank P is 62 cm by 25 cm by 25 cm. Both holes are located at a height of 15 cm from the top of their respective containers. When Tank M is completely filled with water and both buttons are pressed, what will be the final water level in Tank P?
Volume of Tank M to pour into Tank N
= 136 x 55 x 15
= 112200 cm³

Volume of the Tank N that can be filled before overflow
= 55 x 24 x (69 - 15)
= 71280 cm³ 

Volume of water in Tank P
= 112200 - 71280
= 40920 cm³ 

Base area of Tank P
= 62 x 25
= 1550 cm² 

Final height of Tank P
= 40920 ÷ 1550
= 26.4 cm

Answer(s): 26.4 cm
