Container J, measuring 60 cm by 40 cm by 50 cm, was filled with water to the brim. Water was then poured from Container J to Container K, which has a base area of 800 cm² until the height of the water level in Container K became twice that of the water level in Container J. Find the volume of water in Container K, leaving your answer in cubic cm.
Volume of Container J
= 60 x 40 x 50
= 120000 cm³ 

Base area of Container J 
= 60 x 40
= 2400 cm²

Total base areas
= 2400 + 800 + 800
= 4000 cm² 

Height of the water level in Container J after pouring
= 120000 ÷ 4000
= 30 cm

Height of the water level in Container K after pouring
= 2 x 30 
= 60 cm

Volume of water in Container K
= 800 x 60
= 48000 cm³ 

Answer(s): 48000 cm³
