WebIf "B" is a 3x4 matrix, what is the largest possible dimension of the row space of "B"? Matrix "A" has 3 columns. Thus, there can be no more than 3 pivots, which implies that at least one row of "A" in echelon form must be zero. Accordingly, 3 is the largest possible dimension of the row space of "A". Matrix "B" has 4 columns, but only 3 rows.
