According to my sources, a general purpose dry 20 foot container used in ocean cargo is normally 8 ft wide and 8.5 ft high. The volume of that container is the length times the width times the height:
20 x 8 x 8.5 = 1360 cubic feet.
To convert from cubic feet to cubic meters, we can figure out a conversion factor based on the linear relationship: .0254 m = 1 inch. So, 1 cubic foot = (12 x 12 x 12) cubic inches = 1728 cubic inches = 1728*(.0254)3 cubic meters = 0.02832 cubic meters
Multiply the cubic feet by the conversion factor to get cubic meters:
1360(0.02832) = 38.5 cubic meters.
Remember that this assumes no air space left at all after you fill it!
