Alot of ! ! hi, i would greatly appreciate with this. i have no idea how to do it. a marble company has hired you as their new production manager. your job is to choose the form of packaging for a new product from the five choices below. the package must hold at least 400 cubic inches. the cost of the cardboard for the packaging is $0.02 per square inch. you should include the volume, total surface area, and materials cost for each solid given below, including the formulas you used and each step of your work. make sure to use the formulas given in your lessons and round your answers to the nearest hundredth. solid 1 (rectangle): solid 2 (pyramid): solid 3 (cylinder): solid 4 (cone): solid 5 (sphere): write a paragraph that answers the following questions: • do all of the solids hold at least 400 cubic inches? • which solid is the most cost efficient (the packaging with the smallest materials cost that holds at least 400 cubic inches)? • would the most cost efficient solid work well for packaging? why or why not? • which solid would you recommend using? why?

Logically, the answer is the sphere, as it is the figure which gives maximum volume for the same total surface area. But I'll just solve them like you want it.

I'm just writing the numerical values without the units.Please resolve

Solid 1: Square Prism with each side of the base equal to 8 in. and a height of 8 in.

Volume = 8^3 = 512

Area = 8^2 * 6 = 384

V/A Ratio = 1.33 (We need the highest ratio, that's why they hired us)

Cost = $7.68

Solid 2: Square Pyramid with each side of the base equal to 10 in. and a height of 15 in.

Volume = 1/3 * 10^2 * 15 = 500

Slant height = [(10/2)^2 + 15^2]^(1/2) = root of 250 = 15.81

Area = 2*10*15.81 + 10^2 = 416.23

V/A Ratio = 1.20

Cost = $8.34

Solid 3: Cylinder with a radius of 4 in. and a height of 10 in.

Volume = pi*4*4*10 = 502.65

Area = 2*pi*4*4 + 2*pi*4*10 = 351.86

V/A Ratio = 1.43

Cost = $7.04

Solid 4: Cone with a radius of 7 in. and a height of 10 in.

Volume = (1/3)*pi*7*7*10 = 513.13

Slant height = [(7^2)+(10^2)]^(1/2) = 12.21

Area = pi*7*12.21 + pi*7*7 = 422.37

V/A Ratio = 1.21

Cost = $8.45

Solid 5: Sphere with a radius of 5 in.

Volume = (4/3)*pi*(5^3) = 523.60

Area = 4*pi*(r^2) = 314.16

V/A Ratio = 1.67

Cost = $6.28

Hence, Solid 5 must be the packaging model opted for

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

answer: r there any options?
