Tank Q, measuring 70 cm by 30 cm by 58 cm, was filled with water to the brim. Water was then poured from Tank Q to Tank R, which has a base area of 550 cm² until the height of the water level in Tank R became thrice that of the water level in Tank Q. Find the volume of water in Tank R, leaving your answer in cubic cm.
Volume of Tank Q
= 70 x 30 x 58
= 121800 cm³ 

Base area of Tank Q 
= 70 x 30
= 2100 cm²

Total base areas
= 2100 + 550 + 550 + 550
= 3750 cm² 

Height of the water level in Tank Q after pouring
= 121800 ÷ 3750
= 32.48 cm

Height of the water level in Tank R after pouring
= 3 x 32.48 
= 97.44 cm

Volume of water in Tank R
= 550 x 97.44
= 53592 cm³ 

Answer(s): 53592 cm³
