Question

Draw a Problem Analysis Chart (PAC), Interactivity chart ,IPO chart, Algorithmand flowchart for the following problems1. A painter wants to know the amount of paint needed to paint only the walls andthe interior side of the door in a room. The chosen paint covers 100 square feetper gallon.There are two windows. Test the problem with the following data:The room is 12 feet long, 10 feet wide, and 8 feet tall.The two windows are 5 by 3 feet, and 6 by 2 feet, respectively

Answer 1

NOT THE CEILING?

Not the floor

Total surface Area = 2*12*8 + 2*10*8 = 192 + 160 = 352 square feet

352 - 3*5 - 6*2 = 352 - 15 - 12 = 325 square feet

325 /100 = 3.25 gallons
