A scientist produces separate electron micrographs of a bacterial cell and an algal cell.
| Cell | Length on micrograph in mm | Magnification |
|---|---|---|
| bacterial cell | 24 | ×6000\times6000×6000 |
| algal cell | 36 | ×450\times450×450 |
How many bacterial cells, placed end to end, would have the same total length as the algal cell?
