Answer:
729 is a perfect cube. The number whose cube is 729 is 9.
Step-by-step 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.
