Question

Suppose that, from measurements in a microscope, you determine that a certain bacterium covers an area of 1.50 μm2. Convert this to square meters.

Answer 1

1 m = 1 000 000 ym

converted other way we can say that:

1 ym =
`10^(-6)` m

Now, since we have ym^2 which is ym*ym which means:
1 ym^2 =
`(10^(-6)) ^2 = 10^(-12)` m

we have 1,5 ym^2 which means that answer is:

`1.5* 10^(-12) m`
