The first thing we must do for this case is find the area. "room with walls 14 feet long" Therefore, the area is given by: A = (14) * (14) A = 196 feet ^ 2 Then, the number of pails of plaster are given by: n = 196/97 n = 2.02 Rounding off we have: n = 2 Answer: you would need to buy 2 pails of plaster to cover the ceiling of a room with walls 14 feet long
