Tank B, measuring 60 cm by 35 cm by 66 cm, was filled with water to the brim. Water was then poured from Tank B to Tank C, which has a base area of 980 cm² until the height of the water level in Tank C became thrice that of the water level in Tank B. Find the volume of water in Tank C, leaving your answer in cubic cm.
Volume of Tank B
= 60 x 35 x 66
= 138600 cm³ 

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

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

Height of the water level in Tank B after pouring
= 138600 ÷ 5040
= 27.5 cm

Height of the water level in Tank C after pouring
= 3 x 27.5 
= 82.5 cm

Volume of water in Tank C
= 980 x 82.5
= 80850 cm³ 

Answer(s): 80850 cm³
