what are the dimensions of a 55 gallon plastic drum
Drum (container) It is common to hear a drum referred to as a barrel and the two terms are used nearly interchangeably. Many drums have a common nominal volume of 208 litres (55 US gal; 46 imp gal) and nominally measure just under 880 millimetres (35 in) tall with a diameter just under 610 millimetres (24 in) and differ by holding about thirteen gallons more than a barrel of crude oil. In the United States, 25-US-gallon (95 l; 21 imp gal) drums are also in common use and have the same height. This allows easy stacking of mixed pallets. Barrels can be constructed of plastic, laminated paperboard or steel.
