Understanding Cubing a Number

The video tutorial by Mr. J explains the concept of cubing a number, which involves multiplying a number by itself three times. It introduces the terms 'base' and 'exponent' and provides examples using 2 cubed and 5 cubed. The video also explains why the process is called 'cubing' by relating it to the volume of a cube. The tutorial concludes with a summary of the key points covered.
