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.

the saving company have is: 24  *$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

We need to caculate the surface areas of

Box 1 = 2lw+2lh+2hw = 2*20*4 + 2*20*6 + 2*6*4 = 448

Box 2 = 2lw+2lh+2hw = 2*15*8 + 2*15*4 + 2*4*8 = 424

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

448  - 424

= 24  

So the saving company have is: 24  *$1.25 = 30

Hope it will find you well.

answer: get more recipes with 3 magazines for $20! i often use chicken broth instead of water. 3 tablespoons butter, divided; 1/2 cup freshly grated parmigiano-reggiano bring water and salt to a boil in a large saucepan; pour polenta slowly into 5 minutes to thicken; stir and taste for salt before transferring to a serving bowl.

both equations and proportions are better.
