The Speed Math Method for 6-Digit Cube Roots

A 6-digit perfect cube like 636,056 can be solved in seconds: the last digit 6 means the root ends in 6. Dropping the last 3 digits leaves 636 (which sits between 8ยณ = 512 and 9ยณ = 729, giving a tens digit of 8). Answer: 86! This mental method inspires immense confidence in students.
