Tank U, measuring 45 cm by 40 cm by 63 cm, was filled with water to the brim. Water was then poured from Tank U to Tank V, which has a base area of 345 cm² until the height of the water level in Tank V became thrice that of the water level in Tank U. Find the volume of water in Tank V, leaving your answer in cubic cm.
Volume of Tank U
= 45 x 40 x 63
= 113400 cm³ 

Base area of Tank U 
= 45 x 40
= 1800 cm²

Total base areas
= 1800 + 345 + 345 + 345
= 2835 cm² 

Height of the water level in Tank U after pouring
= 113400 ÷ 2835
= 40 cm

Height of the water level in Tank V after pouring
= 3 x 40 
= 120 cm

Volume of water in Tank V
= 345 x 120
= 41400 cm³ 

Answer(s): 41400 cm³
