Answer: chain link fence
Peptidoglycan could be found in high number on gram positive cell walls. The structure of peptidoglycan looks like a cross link which makes it sturdy, so rain coat would be false.

hope this helps :)
The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²
Volume = l³
Volume = (100 x 10⁻⁶)³
Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴
