the saving company have is: 24 $in^{2}$ *$1.25 = 30

Step-by-step explanation:

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.

We need to caculate the surface areas of

Box 1 = 2lw+2lh+2hw = 2*20*4 + 2*20*6 + 2*6*4 = 448 $in^{2}$

Box 2 = 2lw+2lh+2hw = 2*15*8 + 2*15*4 + 2*4*8 = 424 $in^{2}$

So the differences in surface areas of the two boxes is:

448 $in^{2}$ - 424 $in^{2}$

= 24 $in^{2}$

So the saving company have is: 24 $in^{2}$ *$1.25 = 30

Hope it will find you well.

The material used to make a storage box costs $1.25 per square foot. The boxes have the same volume.
