Question

How much more water is needed to fill the tank to its brim?

• A. 2400 ${cm}^3$
• B. 3200 ${cm}^3$
• C. 3600 ${cm}^3$
• D. 6000 ${cm}^3$

Answer 1

Answer: (C)

3600 ${cm}^3$

Capacity of the tank $=$ Volume of tank

$=20\times 20\times 15=6000c{m}^3$

Volume of water filled in the tank $=20\times 8\times 15$

$=2400c{m}^3$

Volume yet to be filled in tank to its brim $=6000c{m}^3-2400c{m}^3$

$=3600c{m}^3$
