Container B, measuring 60 cm by 35 cm by 68 cm, was filled with water to the brim. Water was then poured from Container B to Container C, which has a base area of 990 cm² until the height of the water level in Container C became twice that of the water level in Container B. Find the volume of water in Container C, leaving your answer in cubic cm.
Volume of Container B
= 60 x 35 x 68
= 142800 cm³ 

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

Total base areas
= 2100 + 990 + 990
= 4080 cm² 

Height of the water level in Container B after pouring
= 142800 ÷ 4080
= 35 cm

Height of the water level in Container C after pouring
= 2 x 35 
= 70 cm

Volume of water in Container C
= 990 x 70
= 69300 cm³ 

Answer(s): 69300 cm³
