Final answer:
The concept where the square of a number is multiplied by itself is known as the cubic power of that number.
Step-by-step explanation:
When the square of a number is multiplied by itself, the result is the cubic power of that number. In mathematical terms, if you square a number and then multiply it by itself again, you are effectively raising it to the power of 3. For example, if we take the number 2 and square it, we get 22 which is 2 x 2 = 4. If we multiply 4 (which is the square of 2) by 2 again, we get 23 or 2 x 2 x 2, which equals 8, hence showing the number has been raised to its cubic power. Therefore, the concept described in the question is referred to as a cubic power.
