Tank N, measuring 75 cm by 40 cm by 48 cm, was filled with water to the brim. Water was then poured from Tank N to Tank P, which has a base area of 1000 cm² until the height of the water level in Tank P became thrice that of the water level in Tank N. Find the volume of water in Tank P, leaving your answer in cubic cm.
Volume of Tank N
= 75 x 40 x 48
= 144000 cm³ 

Base area of Tank N 
= 75 x 40
= 3000 cm²

Total base areas
= 3000 + 1000 + 1000 + 1000
= 6000 cm² 

Height of the water level in Tank N after pouring
= 144000 ÷ 6000
= 24 cm

Height of the water level in Tank P after pouring
= 3 x 24 
= 72 cm

Volume of water in Tank P
= 1000 x 72
= 72000 cm³ 

Answer(s): 72000 cm³
