Question : A hall of 10 m in length, 5 m in width, and 6 m in height is to be painted (one side only). Determine the total surface area to be painted. (neglect the area of windows and doors)(floor area is NOT to be painted)
Option 1: 300 m2
Option 2: 280 m2
Option 3: 330 m2
Option 4: 230 m2
Correct Answer: 230 m 2
Solution : Given: Length = 10 m Width = 5 m Height = 6 m Area of 4 walls = 2(l + w)h = 2 × (10 + 5) × 6 = 2 × 15 × 6 = 180 m 2 Area of ceiling = l × w = 10 × 5 = 50 m 2 Total area = 180 + 50 = 230 m 2 Hence, the correct answer is 230 m 2 .
