Container C, measuring 50 cm by 20 cm by 54 cm, was filled with water to the brim. Water was then poured from Container C to Container D, which has a base area of 1000 cm² until the height of the water level in Container D became thrice that of the water level in Container C. Find the volume of water in Container D, leaving your answer in cubic cm.
Volume of Container C
= 50 x 20 x 54
= 54000 cm³ 

Base area of Container C 
= 50 x 20
= 1000 cm²

Total base areas
= 1000 + 1000 + 1000 + 1000
= 4000 cm² 

Height of the water level in Container C after pouring
= 54000 ÷ 4000
= 13.5 cm

Height of the water level in Container D after pouring
= 3 x 13.5 
= 40.5 cm

Volume of water in Container D
= 1000 x 40.5
= 40500 cm³ 

Answer(s): 40500 cm³
