The U.S. Postal Service will accept a box for domestic shipment only if the sum of its length and girth (distance around) does not exceed 108 in.
What dimensions will give a box with a square end the largest possible volume?

Respuesta :

Length could be 6.
Height could be 6.
Girth could be 3. 

6 X 6 = 36
36 X 3 = 108

Hope this helped!
