Question 132
A tall rectangular vessel is half filled with water. The base dimension of the vessel is 62 cm x 45 cm. A heavy metal cube of edge 15 cm is dropped into the vessel. The rise in level of the vessel is:
Solution
Let,say x is the rise level of the cube.
So, Volume of the water that would be filled
$$=62×45× x. $$
Volume of the cube$$=15×15×15=3375cm^3.$$
So, $$62×45×x =3375$$
or, $$X= 1.21(approx).$$
So, A is correct choice.
