Mental Shortcut for 4-Digit Cube Roots

Any 4-digit perfect cube like 2,197 can be solved in 2 seconds mentally: Look at the last digit (7 ➔ ends in 3). Cross out the last three digits, leaving 2 (between 1³ and 2³ ➔ starts with 1). Result: 13! Practicing with these worksheets turns students into mental math wizards.
