Tank T, measuring 80 cm by 35 cm by 32 cm, was filled with water to the brim. Water was then poured from Tank T to Tank U, which has a base area of 400 cm² until the height of the water level in Tank U became thrice that of the water level in Tank T. Find the volume of water in Tank U, leaving your answer in cubic cm.
Volume of Tank T
= 80 x 35 x 32
= 89600 cm³ 

Base area of Tank T 
= 80 x 35
= 2800 cm²

Total base areas
= 2800 + 400 + 400 + 400
= 4000 cm² 

Height of the water level in Tank T after pouring
= 89600 ÷ 4000
= 22.4 cm

Height of the water level in Tank U after pouring
= 3 x 22.4 
= 67.2 cm

Volume of water in Tank U
= 400 x 67.2
= 26880 cm³ 

Answer(s): 26880 cm³
