I removed a cabinet leaving a hole in the floor?

Question

I need to level a floor. Hole is 2' by 3' 6" deep

Answer 1

About half a cube of concrete

Answer 2

Build a frame from 2 x 6 and nail plywood on it.  Then add whatever best matches the rest of the floor.

Answer 3

put the cabinet back... it was obviously there for a reason!

Answer 4

are you saying that when you removed a cabinet that there is now a hole 2 feet square and 3feet 6 inches deep???

Where is this hole----in the basement?

Answer 5

Patch it with some concrete

Answer 6

I'm going to assume the depth is really the thickness of the flooring material down to the sub floor. If that is the case you can use floor leveling compound. Pour or trowel it in the hole.
