Container R, measuring 75 cm by 25 cm by 42 cm, was filled with water to the brim. Water was then poured from Container R to Container S, which has a base area of 775 cm² until the height of the water level in Container S became thrice that of the water level in Container R. Find the volume of water in Container S, leaving your answer in cubic cm.
Volume of Container R
= 75 x 25 x 42
= 78750 cm³ 

Base area of Container R 
= 75 x 25
= 1875 cm²

Total base areas
= 1875 + 775 + 775 + 775
= 4200 cm² 

Height of the water level in Container R after pouring
= 78750 ÷ 4200
= 18.75 cm

Height of the water level in Container S after pouring
= 3 x 18.75 
= 56.25 cm

Volume of water in Container S
= 775 x 56.25
= 43593.75 cm³ 

Answer(s): 43593.75 cm³
