Answer:
Here, l = 7 m, b = 6 m, h = 15 m Volume of cuboid \[=\text{ }l\times b\times h\] \[=\text{ }7\times 6\times 15\] \[=\text{ }630\text{ }{{m}^{3}}\] Since, \[1\text{ }{{m}^{3}}\text{ }=\text{ }1000\text{ }L\] \[\therefore \] Capacity of water in reservoir \[=630\times 1000\] = 630000 L Since, 8400 L water 5 pumped out \[\therefore \]Water left in reservoir \[=\text{ }6300008400\] = 621600 L \[=\text{ }621.6\text{ }{{m}^{3}}\] \[Water\text{ }level\text{ }=\frac{Volume}{Base\text{ }Area}\] \[=\frac{621.6}{7\times 6}\] = 14.8 m Fall in water level \[=\text{ }15\text{ }\text{ }14.8\] = 0.2 m or 20 cm
