A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it

Marina86 [1]

Answer:

Density of rock will be equal to $3.13g/cm^3$

Explanation:

It is given that mass of the rock $m=260gram$

Volume displaced bu rock $V=83cm^3$

We have to find the density of rock

Density is equal to ratio of mass and volume

Therefore density of rock $\rho =\frac{m}{V}$

$\rho =\frac{260}{83}=3.13g/cm^3$

So density of rock will be equal to $3.13g/cm^3$
