Program Background

Some plastic coolers have their walls filled with foam to aid in insulating

the contents of the cooler. To aid the design engineer, this program is

going to estimate how much foam is needed and how much the foam

will weigh for different insulations. The program will need the desired

outside height $(h),$ width $(w),$ depth $($ d $),$ and the wall's thickness $(t).$ To

calculate the volume $(v)$ within the plastic shell, the total volume of the

closed outer box will be calculated and the volume that is filled with air

will be subtracted from it $(v=v_{\text{o}\text{u}\text{t}\text{e}\text{r}}-v_{\text{a}\text{i}\text{r}}).$

The equations for the intermediate volumes are:

$v_{\text{o}\text{u}\text{t}\text{e}\text{r}}=h**w**d$

$v_{\text{a}\text{i}\text{r}}=(h-2**t)**(w-2**t)**(d-2**t)$

The foam's density $(,$ in lb$/$ft ${?}^3)$ and the volume to be filled will be used to find the weight of the foam.

weight $=v**$

The three chemical options for foams are: Polyurethane Foam $)=(1\mathrm{.}8l\frac{b}{f}{t}^3$

Polystyrene Foam $)=(\frac{{3\mathrm{.}1214}^{lb}}{f}{t}^3$

Specialty Mixed Foam $)=(0\mathrm{.}65l\frac{b}{f}{t}^3$

Assignment Description

This program will be estimating the amount of foam needed to fill the cooler's plastic shell and the weight

of that foam for the different chemical foams. The input wall thickness will need to be converted to feet

before calculating the volume inside the plastic shell. The volume will be used to calculate the three

different weights $($one for each chemical$).$ This will require the different density constants to be declared

and assigned a value within the code. The program will neatly display the calculated volume and each

chemical's name with its corresponding weight estimation.

To reduce variables entered by the user, set your width variable to be $2$ ft and your height variable to be

$1\mathrm{.}5$ ft $.$
