Tank G, measuring 65 cm by 30 cm by 54 cm, was filled with water to the brim. Water was then poured from Tank G to Tank H, which has a base area of 520 cm² until the height of the water level in Tank H became thrice that of the water level in Tank G. Find the volume of water in Tank H, leaving your answer in cubic cm.
Volume of Tank G
= 65 x 30 x 54
= 105300 cm³ 

Base area of Tank G 
= 65 x 30
= 1950 cm²

Total base areas
= 1950 + 520 + 520 + 520
= 3510 cm² 

Height of the water level in Tank G after pouring
= 105300 ÷ 3510
= 30 cm

Height of the water level in Tank H after pouring
= 3 x 30 
= 90 cm

Volume of water in Tank H
= 520 x 90
= 46800 cm³ 

Answer(s): 46800 cm³
