The answer is B

Hope this help

Answer 2

The surface area of the hexagonal pyramid is: 790 m²

What is the surface area of the hexagonal pyramid?

The formula for the surface area of a hexagonal pyramid is:

S.A = 3ab + 3bs

Where:

a is apothem

b is base

s is slant height

We are given:

a = 6.5√3

b = 13

s = 9

Thus:
S.A = 3(6.5√3 * 13) + 3(13 * 9)

S.A = 790 m²
