Math problem or Real life would make a difference in the answer. In real life you have to "break the joints" on the floor joists, in a math problem, not so much. Plywood almost universally assumes 4'X8' sheets so 4X8=X sq/feet/per sheet Hint more than 30 sq feet less than 36 13' X 14'= Y sq/feet for the room hint more than 180, less than 186 so looks like the formula will be room size divided by sq feet per sheet Y/X= Answer more than 5 less that 8 sheets, if you are answering in whole sheets round up if not it does have a decimal.
