To determine whether the side lengths of 6 cm, 8 cm, and 10 cm can form a triangle, we can use the triangle inequality theorem. This theorem states that for any three sides of a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Let's check the three conditions:

  1. 6 cm + 8 cm > 10 cm:
    14 > 10 (True)

  2. 6 cm + 10 cm > 8 cm:
    16 > 8 (True)

  3. 8 cm + 10 cm > 6 cm:
    18 > 6 (True)

Since all three conditions of the triangle inequality are satisfied, the side lengths 6 cm, 8 cm, and 10 cm can indeed form a triangle.

The correct response is: They will form a triangle because the sum of any two of the side lengths is greater than the length of the third side.
