Density of any object of found by dividing its Mass by its Volume
So firstly we have to find the Volume
Volume of sphere = [tex] \frac{4}{3} \pi r^{2} [/tex]
where r is radius
So lets find the Volume
Volume of spherical marble = [tex] \frac{4}{3} \pi (1)^{2} [/tex]
= [tex] \frac{4}{3} \pi [/tex]
Now mass = 10 grams
So density = Mass/Volume = [tex] \frac{10}{\frac{4}{3} \pi}= \frac{30}{4\pi} [/tex] rho
≈2.39 rho
