Square and cubic numbers

This task is about recognising square and cubic numbers without using a calculator.

A square number is an integer that can be written as the square of some other integer. So 4 is a square number because 2 × 2 = 22 = 4.

A cubic number is an integer that can be written as the cube of some other integer. So 1000 is a cubic number because 10 × 10 × 10 = 103 = 1000.
