Bridget places a box that is 4x6x8 on the floor. She then places a 2x3x5 box on top of the first box, forming a two-box tower. She will then paint all the surfaces she can paint without moving either of the boxes. She wants to paint as little as possible, so she places the boxes in a way that minimizes the amount she'll have to paint. What is the total area she has to paint? 

 yes this is probably just a simple surface area problem im probably overlooking something :c

Place the 4 x 6 x 8 box on one of the 6x8 sides

   place the 2 x 3 x 5  box on top of it , on one of its 3x5 sides

 

2 x    4 x 6    +    2 x   4x8       +   2x   2 x 3   + 2x  2 x 5       +     3 x 5    +  ( 6x8 - 3x5)       total

 

 

This way she does not paint  a   6x8 face      and a   3x5   face     and  a   3x5 piece of the other 6x8 face
