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. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. Step 1 (2 pts). 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");. Submit for grading to confirm 1 test passes. Ex: If the input is: 12.0

Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:
Question
Transcribed Image Text: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. Complete each step and submit for grading before starting the next step. Only
a portion of tests pass after each step but confirm progress.
Step 1 (2 pts). 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");. Submit for grading to confirm 1 test passes.
Ex: If the input is:
12.0
15.0
29.95
the output is:
Wall area: 180.0 sq ft
Step 2 (2 pts). Calculate and output the amount of paint needed to three decimal places. One gallon of paint covers 350 square feet.
Submit for grading to confirm 2 tests pass.
Ex: If the input is:
12.0
15.0
29.95
the output is:
Wall area: 180.0 sq ft
Paint needed: 0.514 gallons
Step 3 (2 pts). 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 module to round up to the nearest gallon (int). Submit for grading to confirm 4 tests pass.
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 (4 pts). Calculate and output the paint cost, sales tax of 7%, and total cost. Dollar values are output with two decimal places. Submit
for grading to confirm all tests pass.
Transcribed Image Text:Step 4 (4 pts). Calculate and output the paint cost, sales tax of 7%, and total cost. Dollar values are output with two decimal places. Submit

Ex: If the input is:
8.0
8.0
49.20
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
