Question

The material used to make a storage box costs $1.25 per square foot. The boxes have the same volume. How much does a company save by choosing to make 50 of Box 2 instead of 50 of Box 1?
Surface area of Box 1 to the nearest hundredth:


ft2


Surface area of Box 2 to the nearest hundredth:


ft2



Cost of 50 of Box 1 the nearest cent: $



Cost of 50 of Box 2 the nearest cent: $



Using the rounded values above, the company saves $


by using Box 2.

Answer 1

Answer:

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.

My answer:

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.
