Given that it is $3.35 per 2.2 pounds, so per pound, the price would be $0.66.
The correct answer would be $0.66/lb.

Given pyramid with octagonal base. Image of the pyramid attached below:
We know the formula of Lateral Area of pyramid = 
where p represent the perimeter of the octagonal base
and l represent the slant height of the pyramid.
109.9 = 
Solve for p
p = 32.81 cm
Perimeter of octagonal base (all sides are same) = 8*s
where s represent the side of octagon
8s = 32.81
Solve for s
s = 4.1 cm
Side of the octagon = 4.1cm (option D)
