The large cardboard boxes you have seen sitting around (for instance, with watermelons in them at Wal-Mart) are called "gaylord boxes".
They come in several sizes and when they are empty they can be "broken down" for easy reuse or disposal.
While delivering 16,000 pounds of 40% cream to the Fayetteville plant that makes SWANSON tv dinners, I noticed several gaylord boxes. They were about 3ft x 4ft x 3ft. That ends up a little less than 35 cu.ft. after you deduct for the corners that do not extend to a 90* angle.
Inside was 1100 pounds of "macaroni". I just never thought of macaroni weighing that much. The powder for the cheese sauce was on another pallet.
Another surprise was a box of ground black pepper. The box was about 16in x 16in x 12in. Not very large at all, but it contained 50 pounds.
I am often amazed at the things I notice about manufacturing plants I deliver to.
