Container N, measuring 75 cm by 20 cm by 45 cm, was filled with water to the brim. Water was then poured from Container N to Container P, which has a base area of 750 cm² until the height of the water level in Container P became thrice that of the water level in Container N. Find the volume of water in Container P, leaving your answer in cubic cm.
Volume of Container N
= 75 x 20 x 45
= 67500 cm³ 

Base area of Container N 
= 75 x 20
= 1500 cm²

Total base areas
= 1500 + 750 + 750 + 750
= 3750 cm² 

Height of the water level in Container N after pouring
= 67500 ÷ 3750
= 18 cm

Height of the water level in Container P after pouring
= 3 x 18 
= 54 cm

Volume of water in Container P
= 750 x 54
= 40500 cm³ 

Answer(s): 40500 cm³
