Hexagonal pyramid

Find the area of a shell of the regular hexagonal pyramid, if you know that its base edge is 5 cm long and the height of this pyramid is 10 cm.

Correct result:

S =  163.4587 cm2

Solution:

a=5 cm v=10 cm n=6  v2=3/2 a=3/2 54.3301 cm  v3=v2+v22=102+4.3301210.8972 cm  S1=a v32=5 10.8972227.2431 cm2  S=n S1=6 27.2431=163.4587 cm2
