Cells as the basic units of living organisms — practice question

The diameters of living cells show a wide range. A typical eukaryotic cell has a diameter of $1.5 \times 10^{1}\,\mu\text{m}$. A typical prokaryotic cell has a diameter of $7.5 \times 10^{2}\,\text{nm}$. From these values, determine the greatest number of each cell type that could be arranged in a straight line $1\,\text{cm}$ long?
