To cover a rectangle-shaped floor measuring 16x12, you will need 6 4x8 sheets of plywood. Arrange the sheets so that the longer side of the sheets line up along the longer edge of the floor.
Multiply the width by the length, for area. So, 16x12=192Answer:American measured plywood comes in 4x8 sheets. The floor would be 2 sheets long (2x8=16) and 3 sheets wide (4x3=12) so you would need 3x2=6 sheets.
You will need 12.5 sheets of 4x8 plywood.
6 sheets. To figure this out I calculated the square footage of the room (16x12=192) and divided it by the square footage of each sheet of plywood (4x8=32). Answer: 192/32 = 6 sheets.
How much? what kind of plywood floor? Why do you need to do this??
One, if it is big enough.
If you want to raise a sagging floor, you can put a piece of plywood on the floor. You can then add new flooring over the piece of plywood.
I used plywood to build my sentence. That box might be made of plywood or solid wood. The treehouse has a plywood floor.

You would be better of removing the plywood floor completely - and tiling over the original surface.
I need the thickness dimension of 12 ply plywood for floor.
It would depend on the type of floor you are installing. There haven't been enough details about the project provided to answer this question thoroughly. If you are installing engineered hardwood just lay down a 3/4" piece of plywood and a moisture barrier. If you are installing a floating floor, use a moisture barrier and two 1/2" pieces of plywood. see related links
