And my memory was faulty. Of course there were cuts. Either the cuts were so easy they made no impression or so traumatic I've repressed the memory. Maybe I had the HD guy cut them for me?
There were 3 cuts. Two of the fiberboard sheets were cut into two 3' x 8' and two 1 x 8' pieces. The last sheet was cut into two 2' x 8' sheets. There was no need to cut the plywood.
I laid the pieces down so the low side has 7 thicknesses (the plywood counts as 4) and the high side has 0. The stack drops 1/8" with each foot upslope, but the floor rises 1/8", so it evens out. Technically, the low side ended up about an 1/8" too low (one foot upslope is at the same distance from the floor), but this is unnoticeable.
