An Escherichia coli bacterium has a length of 3.5 μm3.5\ \mu\text{m}3.5 μm.
Use the diagram of the T4 bacteriophage below to calculate how many times longer this bacterial cell is than the diameter of the bacteriophage capsid.
On the diagram:
- The scale bar representing 25 nm25\ \text{nm}25 nm measures 1.2 cm1.2\ \text{cm}1.2 cm.
- The diameter of the bacteriophage capsid measures 4.8 cm4.8\ \text{cm}4.8 cm.
