Deer blind floor questions.

Need to replace floor of a wood blind about 4 foot off the ground.

The floor is 5 x 5, how do I make a 60 x 60 inch floor out of a piece of plywood? Since its 48 inches wide, best practice?

I need to re brace with 2 x 4 also.

I used two full sheets of 3/4 plywood cut (in your case) 60" long and ripped 30" wide.



You can see the seam down the middle, I went over the old floor it was a little soft where I always keep my feet.
