Felicia, these questions are tough for a lot of reasons, so it makes sense to me that nobody is giving you the right answers.   here is a right one  :)

Step-by-step explanation:

1st we need a strategy.  brainstorm :P   we are given the cost of material for boxes in area,  we are asked how much 12 boxes would cost.  let's find the area of the material for one box multiply that by the given cost. and then multiply that by 12  for the total cost.  seem good?  Yes there are other good ways to solve this problem if you're thinking that.  this is just how I'm arbitrarily choosing to solve it.

1) surface area of prism box

1a) triangles on ends

1/2* b*p  ( I think 6.2 is P for you, not positive about that)

1/2*6.4*6.2= 19.84  

1b) flat sides

6.4*25 =160 ( this is B )

1c) add up the 5 sides

160*3 + 19.84 * 2  = 839.68

2) find the cost on 1 box

839.68 *  $0.0001 = 0.8397

about $0.84

3) find the cost for 12 boxes

0.8397 * 12 = 10.076

about $10.08

try those answers :)
