Container D, measuring 75 cm by 30 cm by 56 cm, was filled with water to the brim. Water was then poured from Container D to Container E, which has a base area of 750 cm² until the height of the water level in Container E became twice that of the water level in Container D. Find the volume of water in Container E, leaving your answer in cubic cm.
Volume of Container D
= 75 x 30 x 56
= 126000 cm³ 

Base area of Container D 
= 75 x 30
= 2250 cm²

Total base areas
= 2250 + 750 + 750
= 3750 cm² 

Height of the water level in Container D after pouring
= 126000 ÷ 3750
= 33.6 cm

Height of the water level in Container E after pouring
= 2 x 33.6 
= 67.2 cm

Volume of water in Container E
= 750 x 67.2
= 50400 cm³ 

Answer(s): 50400 cm³
