The top of the tower is a regular hexagonal pyramid with a base edge 6.1 meters long and a height 11.7 meters. How many m2 of the sheet is required to cover the top of the tower? We must add 9% of metal for waste.

Correct answer:

S =  256 m2

Step-by-step explanation:

 a=6.1 m v=11.7 m  a2(a/2)2=v22 v2=a23=5.283 m  h2=v2+v22 h=11.72+5.2832=12.837 m  S1=21ah=216.112.837=39.15 m2  S=6S1(1+1009)=639.151.09=256 m2
