Answer:

5x10⁸

Explanation:

Cell = 200 cubic micrometers.

Te question is, how many 200 cubic micrometers are there in a cubic centimeter. 1st, we have to convert 200 cubic centimeter into cubic centimeter:

1cm = 1x10⁴micro, which is the same to:

1x10⁻⁴ cm = 1micro

Now, we have to cube both sides, to "equal the volumes"

(1x10⁻⁴cm)³ = (1micro)³

1x10⁻¹²cm = 1micro³

Multiple both sides by 200:

200 x 1x10⁻¹²cm = 1micro³ x 200

2x10⁻¹⁰cm³ = 200micro³

Finally, 1 cubic cm / 2x10⁻¹⁰cm³ = 5x10⁸
