The shape of the Haemophilus influezae bacteria is a bacteria. The surface area would be gotten by multiplying the length and width.
1 micrometer = 1 * 10^-6 meter
length = 0.25 micrometer = 0.25 * 10^- 6 meter
width = 1 micrometer = 1 * 10^- 6 meter
Surface area = 0.25 * 10^- 6 * 1 * 10^- 6
recall the law of exponents
a^b * a^c = a^(b + c)
Thus,
= 0.25 * 1 * 10^(- 6 + - 6)
Surface area = 0.25 * 10^- 12 meter
