Container B, measuring 45 cm by 30 cm by 45 cm, was filled with water to the brim. Water was then poured from Container B to Container C, which has a base area of 300 cm² until the height of the water level in Container C became thrice 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
= 45 x 30 x 45
= 60750 cm³ 

Base area of Container B 
= 45 x 30
= 1350 cm²

Total base areas
= 1350 + 300 + 300 + 300
= 2250 cm² 

Height of the water level in Container B after pouring
= 60750 ÷ 2250
= 27 cm

Height of the water level in Container C after pouring
= 3 x 27 
= 81 cm

Volume of water in Container C
= 300 x 81
= 24300 cm³ 

Answer(s): 24300 cm³
