Question

Suppose that the box height is h = 2 in. and that it is constructed using 193 \text{in.}^2 of cardboard (i.e., AB = 193). Which values A and B maximize the volume?

Answer 1

if the box is all cardboard, and AB = 193 and h=2, then something doesn't add up, since the surface area is 4(A+B)+2AB
