A 20-foot containerâs overall capacity is 1,170 cubic feet and its maximum gross weight is 6,700 pounds. These limits vary slightly according to where in the world youâre shipping from, so always check with your agent. 20-foot long container is 8 feet 6 inches tall, and 8 feet wide. This gives you an internal space of 19 feet and 4 inches in length, by 7 feet 8 inches in width and 7 feet and 10 inches in height.
CARGO: Our ship hauled 2,800 cargo containers across the Pacific, carrying goods possily worth between $50 and $500 million (our uneducated estimate). No matter which window we looked out of, which deck we stood on, we were always in a sea of cargo containers in the middle of the ocean.RY THIS AT HOME, KIDS: Taking a container ship instead of a plane worked out really well for us.
