(C) According to the Law of Floatation,for a floating body,the weight of the body is equal to the weight of the displaced liquid.Since the mass of the block remains constant,the weight of the block remains constant.Therefore,the weight of the displaced water must also remain constant.Since the weight of the displaced water is equal to $V_{displaced} 	imes ho_{water} 	imes g$,and both $ho_{water}$ and $g$ are constant,the volume of displaced water $(V_{displaced})$ must remain the same.Because the volume of the displaced water does not change,the level of the water in the container will remain the same.

$A$ rectangular block of size $10 \,cm \times 10 \,cm \times 15 \,cm$ is floating in water with the $10 \,cm$ side vertical. If it floats with the $15 \,cm$ side vertical,then the level of water will ..........
