How about:
W = 1
L = 2
H = 2
Not for the first time, I have a sneaking suspicion you may be right; let me check:
V = 4
length = 2 * width
30 cents/sq foot for top and bottom
20 cents/sq foot for sides
V = lwh
Area = top + bottom + sides
Area = length * width + length * width + width * height + width * height + length * height + length * height
Cost = 30 (2 length * width) + 20 (2 width * height + length * height)
Cost = 60 length * width + 40 width * height + 40 length * height
4 = length * width * height
4 = 2 width * width * height
height = 2 / width^2
Cost = 60 * 2 width * width + 40 width * 2 / width^2 + 40 * 2 width * 2 / width^2
Cost = 120 w^2 + 80 / w + 160 / w = 120 w^2 + 240 / w
dC / dw = 240 w - 240 / w^2
Set this equal to zero and solve for w
240 w - 240 / w^2 = 0
w = 1/w^2
w^3 = 1
width = 1 foot
length = 2 feet
height = 2 feet
Cost = 60 + 60 + 40 + 40 + 80 + 80 = 360 cents or $3.60
How about that!

Well, well; who's got a good memory! It's good thank you, I can now produce a 15th Century manuscript, only pen and ink, not gold leaf.
TTH I hope you are feeling much better today.
