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. Write a program to calculate the cost to paint a wall. Amount of required paint is based on the wall Step 1 (2 pts). Read from input wall height, wall width, and cost of one paint can (doubles). Calculate and output the wall's area to one decimal place using System.out.printf ("Wall area: %.1f sq ft\n", area); 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 squar 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 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 celo to round up to the nearest gallon and convert to an integer. Submit for grading to confirm 4 tests pass. Ex If the input is 12.0 15.0 29.95 the output is Wall areal 180.0 sq ft Paint needed: 0.5142 gallons : Cans needed: 1 can (a) 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 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 (a) Paint cost: $49.20 Sales tax: $3.44 Total cost: 552.64 Adat LAB ACTIVITY 2.31.1: LAB Program: Painting a wall 1 #include <iostream> 2 #include <iomanip> 3 #include <cmath> 4 using namespace std; 5 6 int main() { 7 8 9 10 1 11 Type your code here. / return 0; Develop mode Submit mode main.cpp // needed for setprecision() and fixed // needed for ceil() Enter program input (optional) If your code requires input values, provide them here. 0/10 Load default template...
