I think it’s the second answer but just look at the inequality
Given:
Hexagonal Prism dimensions:
Altitude = 6 ft
Regular base;
side = 9 ft
apothem = 7.8 ft
The formula for the lateral surface area of a prism is
LA = P * h
where
LA is the lateral surface area
P is the perimeter of the base
h is the height of the prism
LA = (9 ft * 6 sides) * 6 ft
LA = 324 ft^2
The formula for total surface area is
TA = (P * h) + 2(Ab)
where
TA is the total surface area
Ab = Area of the base
Ab = a * P / 2
Ab = 7.8 ft * (9ft * 6) / 2
Ab = 210.6 ft^2
TA = 324 + 2(210.6)
TA = 745.2 ft^2

The correct answer is B, sorry if it wasn't correct.
