Answer

$2.7m^{2}$

Work Step by Step

The area of skin covering a human body = $2pi\times(0.15m)(2m)+2pi\times(0.15m)^{2}+2\times2pi\times(0.05m)(1m)+2\times2pi\times(0.05m)^{2}=2.7m^{2}$ The contributions of the ends of the cylinders to the total area are small, so for an estimate it would be ok to ignore them.
