27000 = 30³, so cube root is 30.
10648 = 22³, so cube root is 22.
We find this either by prime factorisation or by recognising these as perfect cubes. Both values are exact and whole numbers.

Class 8 Mathematics Textbook Chapter 1 A Square and A Cube question answer
To find cube roots:
27000 = 3 × 3 × 3 × 10 × 10 × 10 = (3×10)³ = 30³ ⇒ √³27000 = 30
10648 = 2 × 2 × 2 × 11 × 11 × 11 = (2×11)³ = 22³ ⇒ √³10648 = 22
So, cube roots are 30 and 22 respectively. Both numbers are perfect cubes.
