By using estimation method, we get:

We make the number into two groups: 056 and 636
$<big>6</big> as the units digit since in 056 the units digit is 6 and only the numbers ending with 6 have their cube's unit digit as 6. 8³ < 636 < 9³ 512 < 636 < 729 The smaller number here is 8, so the tens digit would be <big>8</big>.$

$So, \: \sqrt[3]{636056} = \large{\boxed{86}}$
