Mathematically, six sheets. But in the real world, staggering joints to reduce squeaks and seam problems for a finish material, and maybe some two-by to sister up to exposed joists for better bearing, maybe a few more bucks.

Fun with numbers:

How many posts are needed every eight feet to build an 80 ft fence?
Eleven, if you don't forget the one on the end.

Better yet, if two guys can dig a big hole in two hours,
how many would it take to dig that hole in two seconds?

    Well, 16 feet = 2 * 8 feet. 12 feet = 3 * 4 feet. Thus, 2 * 3 = 6 sheets of plywood is needed.

    3 sheets laid side by side on the 8' edge cover 12' x 8'. 12' x 16' is 2 12' x 8' areas. That means you need a total of 6 sheets.

    Alternately, you can do your homework by computing the square footage of the floor (16 x 12 =192 sq ft) and dividing by the square footage of each sheet (4 x 8 = 32). 192 / 32 = 6.

    Area of room = 16 x 12 = 192 sq.ft.

    Area of sheet = 4 x 8 = 32 sq. ft.

    Now divide 192 by 32 = 6 sheets.

    I would buy 7 sheets to allow for wastage.
