cubes are cubes, son. theyre mainly used as a power exponent at the results of volume problems. reminder: when doing volume and putting down you answer, ALWAYS PUT THE CUBE (OR 3) OR ELSE YOUR ****** MATH TEACHER MARKS IT WRONG!!!!! it's used mainly for volume. it can also be used for exponents in pemdas (aka parenthesis, exponents, multiplication, division, addition, subtraction, or simply known as Please Excuse My Dear Aunt Sally). For example, if theres this: 4 to the 3rd power, this would mean 4*4*4 3 times to make it cubed, which is also known as the answer, which is 64.
There, hopefully this helps, son. Now if you excuse me, I got some Battle ROyale to watch.
