Answer: 117.45 ft²
Step-by-step explanation:
There is a general formula for calculate the surface area of a regular pyramid. This is:
Where p is the perimeter of the base, l is the slant height and B is the area of the base.
The perimeter is:
The base is an hexagon, therefore you can find the area by using the formula for the area of a regular polygon:
The slant height can be calculated with Pythagorean theorem. The hypotenuse is the slant height and the other legs are 6ft and:
Then:
Then, the surface area is:
