Question

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

Answer 1

To convert the area of a bacterium from 1.50µm² to square meters, multiply by (10⁻⁶)² to get 1.50 × 10⁻¹² m².

Step-by-step explanation:

To convert the area of a bacterium from square micrometers to square meters , you can use conversion factors. Since there are 1,000,000 (106) square micrometers in a square millimeter , and 1,000,000 (
`10^6`) square millimeters in a square meter, you can do the conversion by multiplying the area in square micrometers by the conversion factor squared (since area is two-dimensional).

The conversion factor is:

• 1 micrometer (µm) =
  `10{-6}` meters (m)

Therefore, we calculate the area in square meters as:

Area in
`m^2` = Area in µ
`m^2` × (
`10^(-6)` m/µm)

For the given bacterium with an area of 1.50:

Area in
`m^2` = 1.50 × (
`(10^(-6))^2`

Area in
`m^2` = 1.50 ×
`10^(-12)`

Thus, the area of the bacterium in square meters is 1.50 ×
`10^(-12)`
`m^2`.

Answer 2

1,5μm²=1,5×10⁻⁶m² =0,0000015m²
