65. has a property such that a 1.00m3 volume has a mass of 7.86 x10^3 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 $200.0 \mathrm{~g}$.
