Explanation:
We will calculate the specific gravity of the block as follows.
Specific gravity of block = [tex]\frac{\text{block vol below}}{\text{total block vol } \times \text{specific gravity of water}}[/tex]
= [tex]\frac{1.5}{(1.5 + 0.5) \times 1}[/tex]
= 0.75
And, the specific gravity of the solution is as follows.
Specific gravity of solution = [tex]\frac{\text{total block vol}}{\text{block vol below} \times \text{specific gravity of block}}[/tex]
= [tex]\frac{2}{1 \times 0.75}[/tex]
= 1.5
As the given block is rectangular, and its volume is directly proportional to its height and A is not needed in these calculations.
Also, we can note here that the term specific gravity is no longer approved and has been replaced by the term relative density.
