729 is a perfect cube. The number whose cube is 729 is 9.

Explanation:

Let us find the cubes of natural numbers from starting

1 x 1 x 1 = 1

2 x 2 x 2 = 8

3 x 3 x 3 = 27

4 x 4 x 4 = 64

5 x 5 x 5 = 125

6 x 6 x 6 = 216

7 x 7 x 7 = 343

8 x 8 x 8 = 512

9 x 9 x 9 = 729

10 x 10 x 10 = 1000

So we got that 729 is the cube of 9, so 729 is a perfect cube.

The number whose cube is 729 is 9.
