A box of fixed volume v has a square base with side length

Question

1. Find a calculator window in which the graphs of f(x) = x³ + 1000x² + 1000 and g(x) = x³ - 1000x² - 1000 appear indistinguishable.

2. A box of fixed volume V has a square base with side length x. Write a formula for the height, h, of the box in terms of x and V. Sketch a graph of h versus x.
