How many 55 gallon drums will fit in a standard 48' trailer not able to stack?

A standard 48-foot trailer typically has a width of about 8 feet and a height of about 8.5 feet. A 55-gallon drum has a diameter of approximately 2 feet and a height of about 3.5 feet. Given these dimensions, you can fit about 12 drums in a single layer across the width and length (4 drums along the width and 3 along the length), allowing for a total of approximately 36 drums in the trailer without stacking.
