The work need the detailed steps

A square based, box shaped shipping crate is designed to have a volume of 16ft3. The material used to make the base costs twice as much (per ft2) as the material in the sides, and the material used to make the top costs half as much (per ft2) as the material in the sides. What are the dimensions of the crate that minimize the cost of the material? Find the intervals where the function is "increasing" and for "decreasing"? And find the absolute maxima and minima (if possible) h(t) = (5 - t)/(t2 + 2t - 3) interval [-10, 10]. Determine the intervals on which the following function is "concave up", "concave down". Identify any inflection points. h(x) = 2 + cos(2x) for, -pi

Explanation / Answer

We know that the base will have the shape of a square, so its area is b
