Container X, measuring 50 cm by 20 cm by 63 cm, was filled with water to the brim. Water was then poured from Container X to Container Y, which has a base area of 1000 cm² until the height of the water level in Container Y became twice 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
= 50 x 20 x 63
= 63000 cm³ 

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

Total base areas
= 1000 + 1000 + 1000
= 3000 cm² 

Height of the water level in Container X after pouring
= 63000 ÷ 3000
= 21 cm

Height of the water level in Container Y after pouring
= 2 x 21 
= 42 cm

Volume of water in Container Y
= 1000 x 42
= 42000 cm³ 

Answer(s): 42000 cm³
