In the diagram not drawn to scale, Tank R and Tank S each has a button that, when pressed, will cause the water to flow out if the water level is higher than the hole. Tank R measures 128 cm by 47 cm by 141 cm. Tank S measures 56 cm by 21 cm by 51 cm. Tank T is 64 cm by 25 cm by 26 cm. Both holes are located at a height of 14 cm from the top of their respective containers. When Tank R is completely filled with water and both buttons are pressed, what will be the final water level in Tank T?
Volume of Tank R to pour into Tank S
= 128 x 47 x 14
= 84224 cm³

Volume of the Tank S that can be filled before overflow
= 56 x 21 x (51 - 14)
= 43512 cm³ 

Volume of water in Tank T
= 84224 - 43512
= 40712 cm³ 

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

Final height of Tank T
= 40712 ÷ 1600
= 25.445 cm

Answer(s): 25.445 cm
