Container X, measuring 80 cm by 35 cm by 57 cm, was filled with water to the brim. Water was then poured from Container X to Container Y, which has a base area of 840 cm² until the height of the water level in Container Y became thrice that of the water level in Container X. Find the volume of water in Container Y, leaving your answer in cubic cm.
Volume of Container X
= 80 x 35 x 57
= 159600 cm³ 

Base area of Container X 
= 80 x 35
= 2800 cm²

Total base areas
= 2800 + 840 + 840 + 840
= 5320 cm² 

Height of the water level in Container X after pouring
= 159600 ÷ 5320
= 30 cm

Height of the water level in Container Y after pouring
= 3 x 30 
= 90 cm

Volume of water in Container Y
= 840 x 90
= 75600 cm³ 

Answer(s): 75600 cm³
