14. Teria plans to paint the ceiling of an L-shaped room in her apartment. Her ceiling is flat and all adjacent sides meet at right angles, as shown below. She is going to take advantage of a paint sale that discounts the cost of each 1-quart can of paint. Using her painting experience, Teria estimates that each quart of paint covers approximately 100 square feet. Based on her estimate, what is the minimum number of 1-quart cans of paint she must buy to paint 1 coat?
Your Answer is
Correct Answer is H
Explanation
The total area to be painted is 15*18 - 5*10=270-50=220. 1quart paint can paint 100 square feet, so at least 3 buckets of 1-quart paint are needed to paint all the paint, so choose H.
