This was closed, but in case you still need help:

For a cube w/ side length x, the volume would be x^3

applying this logic to our cubes, one has side length 4p and the other has side length 2q^2, so the sum of their volumes would be (4p)^3 + (2q^2)^3. notice that we have a sum of cubes, so you can use

(a+b)^3 = (a+b)(a^2-ab+b^2)

you have the sum of (4p) cubed and (2q) cubed so in this case, your "a" value would be 4p and your "b" value would be 2q. plug these quantities into the sum of cube formula to derive the factored form.
