Question

3.11 Program: Painting a wall (Python 3) (1) Prompt the user to input a wall's height and width. Calculate and output the wall's area. (Submit for 2 points). Enter wall height (feet):12 Enter wall width (feet): 15 Wall area: 180.0 square feet (2) Extend to also calculate and output the amount of paint in gallons needed to paint the wall. Assume a gallon of paint covers 350 square feet. Store this value in a variable. (Submit for 2 points, so 4 points total) Enter wall height (feet): 12 Enter wall width (feet) 15 Wall area: 180.0 square feet Paint needed: 0.5142857142857142 gallons

Explanation / Answer

//program1

#prompt user to input wall's width in feet

paintColors = {

'red':35,

'blue':25,

'green':23

}

wallHeight=float(input('Enter wall height(feet)): '))

wallWidth=float(input('Enter wall width(feet)): '))

areaOfWall = wallHeight * wallWidth

print ("Wall area: ",areaOfWall," square feet")

--------------------------------------------------------------

//output1

Enter wall height(feet)): 12   
Enter wall width(feet)): 15
Wall area: 180.0 square feet   

---------------------------------------------------

//program2

#prompt user to input wall's width in feet

paintColors = {

'red':35,

'blue':25,

'green':23

}

wallHeight=float(input('Enter wall height(feet)): '))

wallWidth=float(input('Enter wall width(feet)): '))

areaOfWall = wallHeight * wallWidth

print ("Wall area: ",areaOfWall," square feet")

#for 350 sq feet 1 gallon required so , gallons needed for areaOfWall is areaOfWall/350

paintRequired = areaOfWall/350

print ("Paint required: ",paintRequired," gallons")

------------------------------

//output2

Enter wall height(feet)): 12   
Enter wall width(feet)): 15
Wall area: 180.0 square feet   
Paint required: 0.5142857142857142 gallons

//program3

#prompt user to input wall's width in feet

paintColors = {

'red':35,

'blue':25,

'green':23

}

wallHeight=float(input('Enter wall height(feet)): '))

wallWidth=float(input('Enter wall width(feet)): '))

areaOfWall = wallHeight * wallWidth

print ("Wall area: ",areaOfWall," square feet")

#for 350 sq feet 1 gallon required so , gallons needed for areaOfWall is areaOfWall/350

paintRequired = areaOfWall/350

print ("Paint required: ",paintRequired," gallons")

cansNeeded =round(paintRequired )

print ("Cans needed: ",cansNeeded," can(s)")

------------------------------------------------------

//output3

Enter wall height(feet)): 12   
Enter wall width(feet)): 15
Wall area: 180.0 square feet   
Paint required: 0.5142857142857142 gallons   
Cans needed: 1 can(s)

cansNeeded =round(paintRequired )

print ("Cans needed: ",cansNeeded," can(s)")

color=input('Choose a color to paint the wall: ')

cost =paintColors[color] * cansNeeded

print("Cost of purchasing ",color, " paint: $", cost)

------------------------------------------------------

//output4

Enter wall height(feet)): 12   
Enter wall width(feet)): 15
Wall area: 180.0 square feet   
Paint required: 0.5142857142857142 gallons   
Cans needed: 1 can(s)
Choose a color to paint the wall: red
Cost of purchasing red paint: $ 35
