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:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get
