2. one of the offices at the company was being repainted. riley’s mother challenged him to figure out how many quarts of paint would be needed. the office is 16 ft long and 12 ft wide, and the height of each wall is 10 ft. the office floor, ceiling, and door are not being painted, and there are no windows in this office. the door opening measures 3 ft by 8 ft. one quart of paint covers . how many quarts of paint are needed to paint the room, if only full quarts can be purchased? show your work.

Not enough information. The question doesn't say how much one quart of paint covers.

EDIT: here's the solution

we have to find the total area of the 4 walls and subtract the area of the door. there are 2 walls with dimensions 16 by 10, and 2 walls with dimensions 16 by 12. so we have: 2(16*10)+2(16*12)=320+384=704 for the area of the walls. now, we can find the area of the door which is 3*8=24. so we subtract the area of the door from the area of the walls, so we have: 704-24=680. Since a quart of paint covers 100, then we divide and get 680/100=6.8 but since we need a whole number of quarts, we round up to get 7 quarts of paint. 

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
