Question

Suppose that you have some rod-shaped bacteria, and each bacterium is 3 micrometers long. If the bacteria were arranged end to end in chains, how many would it take to form a chain that is 6 centimeters long?

Answer 1

Answer:

Number of bacteria required $= 20000$

Explanation:

Given -

Size of each bacterium $= 3$ micrometers long

These bacteria are arranged end to end.

The size of chain to be formed is equal to $6$ centimetres

Let us say that in forming a chain of $6$ centimetres nearly X number of individual bacterium are required.

hence, number of bacterium required to form $6$ centimetres  chain can be represented as

$X = \frac{6 * 10000}{3} \\X = 20000$

Number of bacteria required $= 20000$
