Here cube means:- Multiplying a number 3 times.
for example:-cube of number 2
we have to multiply it 3 times
2×2×2=8
so,here the cube of 2 is 8
similarly cube of 4 is 64
How?By Multiplying it 3 times
4×4×4=64
Next Cube root
8 is a cube root of 2
27 is a cube root of 3
Now,Here are some cubes for you
1=1
2=8
3=27
4=64
5=125
6=216
7=343
8=512
And yes cubes can be negative also like
-9×-9×-9=-729
If we have know what is the cube root of 30 which is not a perfect cube
we have to see in which cube number is close to it
3=27 4=64
so 30 is between 3 and 4
hope it will help you
