I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My
We need to caculate the surface areas of
Box 1 = 2lw+2lh+2hw = 2*20*4 + 2*20*6 + 2*6*4 = 448![in^{2}](/tpl/images/0589/8934/dae19.png)
Box 2 = 2lw+2lh+2hw = 2*15*8 + 2*15*4 + 2*4*8 = 424![in^{2}](/tpl/images/0589/8934/dae19.png)
So the differences in surface areas of the two boxes is:
448
- 424![in^{2}](/tpl/images/0589/8934/dae19.png)
= 24
So the saving company have is: 24
*$1.25 = 30
Hope it will find you well.
