A) \[\text{218 }c{{m}^{3}}\]
B) \[\text{156 }c{{m}^{3}}\]
C) \[\text{228 }c{{m}^{3}}\]
D) \[\text{192 }c{{m}^{3}}\]
Correct Answer: B
Solution :
Volume of water needed to fill the tank to a height of 4 cm \[=(8\times 6\times 4)\,\,c{{m}^{3}}=192\,c{{m}^{3}}\] Volume of the stone \[=36\text{ }c{{m}^{3}}\] \[\therefore \]Volume of water needed \[=192-36=156\text{ }c{{m}^{3}}\]
