To find the cost of plastering the walls and ceilings , we must first find area to be plastered. This would be ( area of room) minus ( area of doors, windows, baseboard):
(40* 36 * 22) - 1375 =30305
Take this number and multiply by the cost per square yard :
30305 * 8.99 = $272 441. 95
Rounding to the nearest dollar, we get $ 272 442; this is because $272 441. 95 is closer to $ 272 442 than $ 272 441.
