Mass Loaded Vinyl

Plywood / MDF Board Action?

I am building a floating floor to help with soundproofing a rehearsal room. Using 2x4 as the beams, and bought 3 / 4 "thick 4 'x 8 'T & G plywood subfloor, then Mass Loaded Vinyl mat, then 3 / 4 "thick 4' x 8 'MDF. The space is a perfect 8 'x 8', so I thought it would be easy to build, but the T & G wood is actually 48 "from the tip of the tongue, so actually 47 1 / 2 "wide, and the MDF is 49" x 97 ", an inch wider in each direction. Why do these different dimensions (such as the 2x4 actually 1.5 x 3.5) and how they are used in construction? Will I have to cut an inch along the width and the enitre length of the MDF?

mesurment board itself is set for construction, as a 2 x 4 is 1.5 wide, so when you add 1 / 2 "You have 2 inch
