1. The problem is to find the cube of a number, which means multiplying the number by itself three times. 2. The formula for the cube of a number $x$ is: $$x^3 = x \times x \times x$$ 3. For example, if the number is 2, then: $$2^3 = 2 \times 2 \times 2$$ 4. Calculate step-by-step: $$2 \times 2 = 4$$ $$4 \times 2 = 8$$ 5. Therefore, the cube of 2 is 8. This method applies to any number you want to cube.
