Calculate the mass of a solid iron sphere that has a diameter of $3.00 \mathrm{~cm}$.
Iron has a property such that a $1.00-\mathrm{m}^{3}$ volume has a mass of $7.86 \times 10^{3} \mathrm{kg}$ (density equals $7.86 \times 10^{3} \mathrm{kg} / \mathrm{m}^{3} ) .$ You want to manufacture iron into cubes and spheres. Find (a) the length of the side of a cube of iron that has a mass of 200.0 $\mathrm{g}$ and (b) the radius of a solid sphere of iron that has a mass of 200.0 $\mathrm{g}$ .
