$3\mathrm{.}20$ LAB$*$: Program: Painting a wall $-$ Fall $2024$

Output each floating$-$point value with two digits after the decimal point, which can be achieved as follows:

print$(\text{'}\{$:$\mathrm{.}2$f$\}\text{'}.$format$($your$\_$value$))$

$(1)$ Prompt the user to input a wall's height and width. Calculate and output the wall's area $($integer$).$ You will need to multiply the width by the height to do this.

Hint: The first variable is assigned for you, and print statement is started for you. You will need to finish creating the variables and complete the print statement.

Hint: You will need to use the $.$format function to format your print statement. $($Submit for $2$ points$).$

Enter wall height $($feet$)$:

$12$

Enter wall width $($feet$)$:

$15$

Wall area: $180$ square feet

$(2)$ Extend to also calculate and output the amount of paint in gallons needed to paint the wall $($floating point$).$ Assume a gallon of paint covers $350$ square feet. Store this value in a variable.

Hint: Output the amount of paint needed using the $.$format function with the $\%$f conversion specifier. This will display the gallons as a float with two decimal places. $($Submit for $2$ points, so $4$ points total$).$

Enter wall height $($feet$)$:

$12$

Enter wall width $($feet$)$:

$15$

Wall area: $180$ square feet

Paint needed: $0\mathrm{.}51$ gallons

$(3)$ Extend to also calculate and output the number of $1$ gallon cans needed to paint the wall. Hint: Use the math.ceil$()$ function to round up to the nearest gallon. You will want to put your variable that you are rounding up in the parentheses of the math.ceil$()$ function.

Hint: You will need to use the $.$format function to format your print statement. $($Submit for $2$ points, so $6$ points total$).$

Enter wall height $($feet$)$:

$12$

Enter wall width $($feet$)$:

$15$

Wall area: $180$ square feet

Paint needed: $0\mathrm{.}51$ gallons

Cans needed: $1$ can$($s$)$

$(4)$ Extend by prompting the user for a color they want to paint the walls. Calculate and output the total cost of the paint cans depending on which color is chosen.

Hint: Use the dictionary item THAT IS ALREADY CREATED FOR YOU to associate each paint color with its respective cost. Red paint costs $$35$ per gallon can, blue paint costs $$25$ per gallon can, and green paint costs $$23$ per gallon can.

Hint: To determine the total paint cost you will need to multiple the paint cost for your wall color by the number of cans needed that you calculated in step $3.$

Hint: You will need to use the $.$format function to format your print statement. $($Submit for $2$ points, so $8$ points total$).$

Enter wall height $($feet$)$:

$12$

Enter wall width $($feet$)$:

$15$

Wall area: $180$ square feet

Paint needed: $0\mathrm{.}51$ gallons

Cans needed: $1$ can$($s$)$

Choose a color to paint the wall:

red

Cost of purchasing red paint: $$35$
