WebFrom a geometrical standpoint, a 3x2 matrix encodes the transformation of a vector from R 2 to R 3. The determinant of a 2x2 matrix encodes the scaling of any region of area in R 2 while the analog for a 3x3 matrix encodes the scaling of any region of volume. You can see that this analogy breaks down when you transform between dimensions.
