Question

A cubic box is 5 inches on each side. If each dimension is increased by x inches, What is the polynomial function that models the new volume V? (V=LWH)

Answer 1

It's a cube, so you know all sides are equal.

If x inches is added to all sides, you have x + 5 for each side.

This means that L = x + 5, H = x + 5, and W = x + 5.

So, if you want the volume plug the values in the formula you have above and that will be your answer.

Answer 2

Thanks a lot!!
