One of the offices at the company was being repainted. Riley’s father challenged him to figure out how many quarts of paint would be needed. The dimensions of the office are 16 ft by 12 ft by 10 ft. The office floor, ceiling, and door would not be painted and there are no windows in this office. The door opening measures 3 ft by 8 ft. One quart of paint covers 100 ft2. How many quarts of paint would be needed to paint the room, if only full quarts can be purchased? Show your work.

it doesnt say anything about the window are height

solomonzelman · Answer

the idea of this problem is:
+ find the entire surface area (of this "cube).
+ exclude the area of that the windows ceiling and door take since they are not colored.
+ divide the remaining area (that will have to be colored) by 100 (ft^2), and any decimal, round up (not round down), no matter how small the remainder from the division is.

will assume it has no windows, but even then I don't know which surface would be the ceiling, so that I can excludde it.
