Length = 2.1m breadth = 1.5m (given) We know volume of the cuboid = Length x breadth x height $$ herefore$$ Rise in water is given by, Length x breadth x height = 630 litres (or) $$frac{630}{1000} m^{3}$$
2.1 x 1.5 x h = $$frac{630}{1000} Rightarrow h = (frac{63}{100})(frac{10}{21})(frac{10}{15})$$ $$Rightarrow$$ h = 0.2 m Hence, option D is the correct answer.
