Density of any object of found by dividing its Mass by its Volume

So firstly we have to find the Volume

Volume of sphere = \frac{4}{3} \pi r^{2}

where r is radius

So lets find the Volume

Volume of spherical marble = \frac{4}{3} \pi (1)^{2}

= \frac{4}{3} \pi

Now mass = 10 grams

So density = Mass/Volume = \frac{10}{\frac{4}{3} \pi}= \frac{30}{4\pi} rho

≈2.39 rho
