What number is the cube of 4 multiplied by 2?

1. 16

2. 64

3. 8

4. 25

The correct answer is: 64

To find the correct solution, first, we need to calculate the cube of 4. The cube of a number is found by multiplying that number by itself two additional times. Therefore, the cube of 4 can be calculated as follows: 4 × 4 × 4 = 16 × 4 = 64. Next, we take this result and multiply it by 2: 64 × 2 = 128. Thus, when we perform the operation of cubing 4 and then multiplying by 2, we arrive at 128. However, since the correct answer needs to be determined from the given choices, it appears that none of those options directly reflect our calculated product. It’s possible there was a misunderstanding in selection or calculation of the final numerical result desired from the question. To clarify, the operation is performed correctly, yielding 128 for the cube of 4 multiplied by 2. In a normal context without ambiguity in question prompt or error in options, 128 would be the answer, based on the chosen mathematical operations executed in sequence.
