Tank X, measuring 60 cm by 40 cm by 66 cm, was filled with water to the brim. Water was then poured from Tank X to Tank Y, which has a base area of 520 cm² until the height of the water level in Tank Y became thrice that of the water level in Tank X. Find the volume of water in Tank Y, leaving your answer in cubic cm.
Volume of Tank X
= 60 x 40 x 66
= 158400 cm³ 

Base area of Tank X 
= 60 x 40
= 2400 cm²

Total base areas
= 2400 + 520 + 520 + 520
= 3960 cm² 

Height of the water level in Tank X after pouring
= 158400 ÷ 3960
= 40 cm

Height of the water level in Tank Y after pouring
= 3 x 40 
= 120 cm

Volume of water in Tank Y
= 520 x 120
= 62400 cm³ 

Answer(s): 62400 cm³
