**Steve**, Thursday, February 16, 2012 at 6:35pmLet the width be x

Then the length is 2x

so, 2(x+2x) = 60

6x = 60

x = 10

so, the box is 10x20

The area of the top is 10*20 = 200, as is the bottom.

There are two sides 10x40 = 2*400 = 800

and 2*20*40 = 1600

top and bottom cost 400*.05 = $20

faces cost .015*2400 = $36

Total cost: $56
