A) \[81\,\,c{{m}^{2}}\]
B) \[625\,\,c{{m}^{2}}\]
C) \[125\,\,c{{m}^{2}}\]
D) \[50\,\,c{{m}^{2}}\]
Correct Answer: C
Solution :
Volume of water in a tank \[=625\,\,c{{m}^{3}}\] Height of the water level\[=5\,\,cm\] \[\therefore \]Base area\[\text{=}\frac{\text{Volume}}{\text{Height}}\] \[\text{=}\frac{\text{625}\,\,\text{c}{{\text{m}}^{\text{3}}}}{\text{5}\,\,\text{c}{{\text{m}}^{\text{3}}}}\text{=125}\,\,\text{c}{{\text{m}}^{\text{2}}}\]
