A cube-shaped silver nanoparticle is used in antibacterial coatings and has sides of length 35 nm35\text{ nm}35 nm.
Calculate the surface area to volume ratio for this nanoparticle. Use the equation:
ratio=surface area÷volume \text{ratio} = \text{surface area} \div \text{volume} ratio=surface area÷volumeA bacterium has a width of 2500 nm2500\text{ nm}2500 nm. Calculate how many of these silver nanoparticles would fit side-by-side across the width of the bacterium. Give your answer to 2 significant figures.
