Answer 4

1000^3 = 1,000,000,000 Way too big.
100^3 = 1,000,000 Much closer
120^3 = 1,728,000 Much closer
130^3 = 2,197,000 Over shot.
125^3 = 1,953,125 Whoops! Tripped over it.

Didn't much like that method.

Much prefer: 1953125 = 5*390625 = (5^2)*78125 = (5^3)*15625 = (5^4)*3125 = (5^5)*625 = 5^9

Prime Factorization.

The cube root of 5^9 is immediate, 5^3 = 125
