In the diagram not drawn to scale, Container K and Container L each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Container K measures 136 cm by 50 cm by 150 cm. Container L measures 57 cm by 21 cm by 60 cm. Container M is 70 cm by 20 cm by 23 cm. Both holes are located at a height of 14 cm from the top of their respective containers. When Container K is completely filled with water and both buttons are pressed, what will be the final water level in Container M?
Volume of Container K to pour into Container L
= 136 x 50 x 14
= 95200 cm³

Volume of the Container L that can be filled before overflow
= 57 x 21 x (60 - 14)
= 55062 cm³ 

Volume of water in Container M
= 95200 - 55062
= 40138 cm³ 

Base area of Container M
= 70 x 20
= 1400 cm² 

Final height of Container M
= 40138 ÷ 1400
= 28.67 cm

Answer(s): 28.67 cm
