A polynomial in the form
is called a sum of cubes
so
Let's verify each case to determine the solution
<u>case A)</u> 
we know that




-------> is not a perfect cube

therefore
the case A) is not a sum of cubes
<u>case B)</u> 
we know that
-------> is not a perfect cube



-------> is not a perfect cube

therefore
the case B) is not a sum of cubes
<u>case C)</u> 
we know that
-------> is not a perfect cube




therefore
the case C) is not a sum of cubes
<u>case A)</u> 
we know that





Substitute


therefore
<u>the answer is</u>
is a sum of cubes
