Find a formula c(x, y,z) that gives the cost of materials for a closed rectangular box, with dimensions in feet. assume that the material for the top and bottom costs $3 per square foot and the material for the sides costs $5 per square foot. show all work in steps clearly.

C(x,y,z)=6*x*y+10*x*z+10*y*z

Step-by-step explanation:

Lets assume that x is width, y is length and z is height. To find the area of the top and bottom surfaces we need to simply multiply length and width.

x*y

There is a 2 surface exist (top and bottom) we need to multiply this value with 2 again.

2*x*y

and the cost is 3$ for per square foot and the cost for top and bottom is:

6*x*y$

Surface areas of side surfaces are multiply of width, height and length, height:

x*z+y*z

There are 4 side surfaces exist. Therefore the are need to be multiply with 2.

2*x*z+2*y*z

and the cost is 5$ for per square foot and the cost for side surfaces is:

10*x*z+10*y*z

Total equality for cost is C(x,y,z)=6*x*y+10*x*z+10*y*z

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
