(8 min) x ( day/1,440 min) x (20 /day) x (365 da/yr) x (35 yr)  = 

      (8 x 20 x 365 x 35) / (1,440)  days =

                (2,044,000) / (1,440)  days =

                             1,419-4/9  days  =  3.89 years

            Rounded to the nearest year:  <em>4 years</em>

At a pack a day for 35years, I would have expected more than
4 years' damage.  But I've checked my math and haven't found
the mistake, so I'll let that be my answer.

valkas [14]
We know that

[volume of a <span>regular hexagonal prism]=[area of the base]*height
height=volume/area of the base
h=160/64-----> 2.5 m

[surface area </span><span>hexagonal prism]=2*[area of the base]+[perimeter of base]*h
</span>[surface area hexagonal prism]=2*[64]+[30]*2.5----> 203 m²

the answer is
