Calculating the cable requires some parameters to be considered such as;

1) Length
2) Temperature of environment
3) Buried, lay in cable tray or lay in conduit.
4) To be laid with other power cables or single (grouping factor)
5) Starting current of motor.

Provide more parameters then we would be able to reply correctly.
