cubic meters of a 20 foot shipping container
Twenty-foot equivalent unit As the TEU is an inexact unit, it cannot be converted precisely into other units. The related unit forty-foot equivalent unit, however, is defined as two TEU. The most common dimensions for a 20-foot (6.1 m) container are 20 feet (6.1 m) long, 8 feet (2.44 m) wide, and 8 feet 6 inches (2.59 m) high, for a volume of 1,360 cubic feet (39 m3). However, both 9-foot-6-inch-tall (2.90 m) High cube and 4-foot-3-inch (1.30 m) half height containers are also reckoned as 1 TEU.[2] This gives a volume range of 680 to 1,520 cubic feet (19 to 43 m3) for one TEU.
Hindenburg-class airship The Hindenburg class were built to an all-duralumin design. The leader of the design team was Dr. Ludwig Dürr, who had overseen the design of all Zeppelins except LZ-1 (on which he was a crew member), under the overall direction of Hugo Eckener, the head of the company. They were 245 m (804 ft) long and 41 m (135 ft) in diameter, longer than three Boeing 747s placed end-to-end, longer than four Goodyear GZ-20 "blimps" end-to-end, and only 24 m (79 ft) shorter than the RMS Titanic. The previous largest civilian airship, with a length of 237 m (777 ft) and a width of 40 m (130 ft), was the British R101, which was completed in 1929. The US Navy's Akron and Macon were 239 m (785 ft) long and 44 m (144 ft) wide.
