19. A box with a square base and no top is to be made from a square piece of cardboard by cutting out a 3 inch square from each corner and folding up the sides. If the box is to hold 75 cubic inches, what size piece of cardboard should be used?
Numerical approximations to integrals typically get better -- i.e., their error goes down -- proportional to a power of N, the number of subintervals in the interval of integration. For the upper and lower sums, the error typically goes down like 1/N as N increases. For the midpoint and trapezoidal rules, the error typically goe
