6. surface area= 8ft*3ft*2 +3ft*2ft*2 +8ft*2ft*2
8.area of the sides= 3.5in*2in *5
area of the base is =S^2 N/4tan (180/N)..........S, is length of sides, N is number of sides
=2^2 * 5/4tan 36
there are s bases so toal surface area=13.74in ^2
Total area of the prism = 35in^2 + 13.74in^2
=48.74 in ^2
