Is there a shortcut to solve this?
Yes, there is, if you know
the first five cubes:
1³ = 1
2³ = 8
3³ = 27
4³ = 64
5³ = 125
plus the fact that 10³ = 1000
So from knowing that,
10³ = 1000
20³ = 8000
30³ = 27000
40³ = 64000
50³ = 125000
The cube root of 34595 lies between 27000 and 64000,
so 34595 lies between 30³ and 40³. So its cube root
lies between:
d) 30 and 40
