Tank Y, measuring 60 cm by 35 cm by 51 cm, was filled with water to the brim. Water was then poured from Tank Y to Tank Z, which has a base area of 980 cm² until the height of the water level in Tank Z became thrice that of the water level in Tank Y. Find the volume of water in Tank Z, leaving your answer in cubic cm.
Volume of Tank Y
= 60 x 35 x 51
= 107100 cm³ 

Base area of Tank Y 
= 60 x 35
= 2100 cm²

Total base areas
= 2100 + 980 + 980 + 980
= 5040 cm² 

Height of the water level in Tank Y after pouring
= 107100 ÷ 5040
= 21.25 cm

Height of the water level in Tank Z after pouring
= 3 x 21.25 
= 63.75 cm

Volume of water in Tank Z
= 980 x 63.75
= 62475 cm³ 

Answer(s): 62475 cm³
