It would be beneficial for you to try it.
Use 10, 20 & 30 cm

"The triangle inequality" requires that any of the tree sides of a triangle is shorter than the sum of the lengths of the two other sides.
In your case 60 = 20 + 40.
The side of 60 cm length is NOT shorter than the sum of the lengths of the two other sides (20 and 40).
On the "triangle inequality" see the lesson
