Question

Hi need help with this problem. The program I'm using is python.

3.17 LAB*: Program: Painting a wall
Program Specifications Write a program to calculate the cost to paint a wall. Amount of required paint is based on the wall area. Total cost
includes paint and sales tax.
Note: This program is designed for incremental development.
Step 1
Read from input wall height, wall width, and cost of one paint can (floats). Calculate and output the wall's area to one
decimal place using print (f"wall area: {wall_area:.1f} sq ft");
Ex: If the input is:
12.0
15.0
29.95
the output is:
Wall area: 180.0 sq ft
Step 2
Ex: If the input is:
12.0
15.0
29.95
Calculate and output the amount of paint needed to three decimal places. One gallon of paint covers 350 square feet.
the output is:
Wall area: 180.0 sq ft
Paint needed: 0.514 gallons

Step 3
Calculate and output the number of 1 gallon cans needed to paint the wall. Extra paint may be left over. Hint: Use ceil() from
the math mouule to round up to the nearest gallon (int).
Ex: If the input is:
12.0
15.0
29.95
the output is:
Wall area: 180.0 sq ft
Paint needed: 0.5142 gallons
Cans needed: 1 can (s)
Step 4
Ex: If the input is:
8.0
8.0
49.20
Calculate and output the paint cost, sales tax of 7%, and total cost. Dollar values are output with two decimal places.
the output is:
Wall area: 64.0 sq ft
Paint needed: 0.183 gallons
Cans needed: 1 can (s)
Paint cost: $49.20
Sales tax: $3.44
Total cost: $52.64

Expert Solution

Step 1

The Algorithm of the code:-

1. Read the wall height, width, and cost of a paint can and store the values in variables.
2. Calculate the wall area by multiplying the height and width, and storing the value in a variable.
3. Calculate the amount of paint needed by dividing the wall area by 350 and store the value in a variable.
4. Calculate the number of cans needed by rounding up the amount of paint needed and store the value in a variable.
5. Calculate the paint cost by multiplying the cost of a paint can by the number of cans needed, and store the value in a variable.
6. Calculate the sales tax by multiplying the paint cost by 0.07, and store the value in a variable.
7. Calculate the total cost by adding the paint cost and sales tax, and store the value in a variable.
8. Output the wall area, paint needed, cans needed, paint cost, sales tax, and total cost.
