Tank T, measuring 55 cm by 20 cm by 63 cm, was filled with water to the brim. Water was then poured from Tank T to Tank U, which has a base area of 825 cm² until the height of the water level in Tank U became twice 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
= 55 x 20 x 63
= 69300 cm³ 

Base area of Tank T 
= 55 x 20
= 1100 cm²

Total base areas
= 1100 + 825 + 825
= 2750 cm² 

Height of the water level in Tank T after pouring
= 69300 ÷ 2750
= 25.2 cm

Height of the water level in Tank U after pouring
= 2 x 25.2 
= 50.4 cm

Volume of water in Tank U
= 825 x 50.4
= 41580 cm³ 

Answer(s): 41580 cm³
