Given: one side of triangle = 6 cm second side of triangle = 10 cm concept used: the difference of two other sides < x < sum of two other side calculation: (10−6)<x<(10+6) ⇒4<x<16 the third side of the triangle should lie between 4 and 16 ∴ minimum integral value is 5 and maximum integral value is 15 Hence, the answer is 5 cm
