a.
0.39
b.
0.82
c.
0.97
d.
1.04

The main formula of the surface area of a right prism is A = 2 x (w x h + l x w + l x h) , where w=7, l=8, and h=4, so the surface area value is A=2(7x4+8x7+8x4)=2(28+56+32=2x116=232. Besides, the volume of a right prism can be calculated with the formula V= l x w x h =8x 7x 4 = 224. Finally the ratio of the surface area to the volume is A / V= 232 / 224 = 1.04. the true answer is D
