20.1
The cube root is the side of a cube.
4
cube root (pi) = 1.46459189.
The cube root of 0.027 is 0.30000000000000004
50 is the cube root of 125,000

I'd say 2.1 or 2.
203 = 8000 Let f(x) = 8132 - x3 then f'(x) = the derivative of f(x) = -3x2 Using Newton-Raphson method, a better estimate is 20 - f(x)/f'(x) = 20 - 132/(-3*202) = 20 + 132/1200 = 20 + 11/100 = 20.11
What approximation is "best" depends on the required level of accuracy.

There is no "best" approximation. The square root is irrational and so it is a non-terminating, non-recurring decimal so adding one more digit will always make it a better approximation.
√40108 = 200.269817996
3.16227766 which is about 3.2
The best approximation for the square root of 3 is approximately 1.732. This value can be rounded to 1.73 for simpler calculations. For more precision, 1.73205 can be used.
