Answer:
648 multiply by 9 to get perfect cube is 5832
Step-by-step explanation:
648 = 2×2×2 × 3×3×3×3
To have a perfect cube, a number should have prime factors in groups of threes.
648 = (2×2×2) × (3×3×3) × 3
So we need two more of 3s, ex., (3×3) to complete the cube
So,
648 ×(3×3)= (2×2×2) × (3×3×3) × 3 ×(3×3)
5832 = (2×2×2) × (3×3×3) × (3×3×3)
cube root of 5832 = (2)×(3)×(3) =18
So, you need to multiply 648 by 9 to get a perfect cube, 5832
