Answer:
k = 75
Explanation:
Factorize 360
360 = 36 * 10
= 2 * 2 * 3 * 3 * 2 * 5
As 360k is cube number, k = 3 * 5 * 5
360k = 360 * 75 = 27000 is a perfect cube
Answer: k = 75

6 6 2 5
2 3 2 3
Prime factorization of 360 is: 2³ · 3² · 5
Since we want a perfect cube, every number must be to the power of 3.
That means we need a 3 and 2 more 5s to make a cube
k = 3 × 5 × 5
= 75
