Answer 2

512 is a perfect cube because 512 = 8 times 8 times 8

Explanation:

A perfect cube is a number that can be rewritten as a product of three identical numbers.

For example: 8 is perfect cube as 8 can be rewritten as:

8 = 2 × 2 × 2

So, from the definition of the perfect cubes, the option that matches it is third option.

512 is a perfect cube as it can be expressed as the product of 8 three times.

512 = 8 × 8 × 8

Therefore, third option is correct.

All the remaining options doesn't fulfill the definition of perfect cubes.
