Transportation Corps Practice Exam

The idea being tested is how many items of different fixed lengths can fit along the 20-foot length of a container. Each type has a specific length along the container’s length, and the goal is to fill the 20 feet exactly with whole units. Eight Quadcons fit because the Quadcon’s length along the container adds up so that 20 feet divided by Quadcon length is 8. Four Tricons fit because 20 feet divided by the Tricon length is 4. Two Bicons fit because 20 feet divided by the Bicon length is 2. In other words, their lengths are such that they divide the 20-foot length exactly: 20 = 8 × (Quadcon length) = 4 × (Tricon length) = 2 × (Bicon length). This exact divisibility is why eight Quadcons, four Tricons, and two Bicons are the correct fit. Other options would leave leftover space if that same packing rule is applied.
