Since we know that triangle inequality theorem states that sum of any two sides of a triangle must be greater than third side.

Now let us see if it is true for our given side lengths.

$10.6+5.6>4.0$

$16.2>4.0$

Now let us try with another pair.

$5.6+4.0>10.6$

$9.6$

We can see that sum of 5.6 and 4 is less than 10.6. Therefore, 10.6 cm, 5.6 cm and 4.0 cm can not be side lengths of a triangle.
