Step-by-step explanation: To solve this question we will work with the conversion from cm to mm as follows

Step 1: First let's convert our length from cm to mm to be able to visualize our problem better as follows

Step 2: Now once the cube has all the sides equal we can use the cube's volume formula to calculate as follows

Step 3: Now all we have to do is to transform back to cm if we want to get the volume in centimetres

Final answer: So the final answer is
