Answer 1

Explanation:

Relative density is the ratio of density of object to density of water. so this statement means that density of iron is 7.8 times more than water or density of iron/density of water =7.8.

PLEASE MARK AS BRAINLEST.

Answer 2

Proper explanation is given below .

To answer this question , one should should know what actually relative density is :

Relative density of a substance is given by :

$\text{Relative Density}=\dfrac{\text{Mass of any volume of substance}}{\text{Mass of an equal volume of water}}$

So , relative density of 8.7 means that for same volume of water mass of iron is 8.7 times that of water .

Hence , this is the requires solution .
