A standard 1 3/4 cross lay has a maximum length of 300 feet. Which of the following statements is true?

A standard 1 3/4 cross lay has a maximum length of 300 feet. Which of the following statements is true?

• A. 250 ft
• B. 275 ft
• C. 290 ft
• D. 300 ft

Answer: (D)

The key idea is that a cross lay has a defined upper limit for how long the hose can be deployed. If the maximum length is 300 feet, the statement that matches this limit is true because it specifies the furthest allowable length you can stretch the hose while staying within the design specifications. Shorter lengths, while also feasible under that limit, don’t convey the maximum capacity and therefore aren’t as direct a match to the question. In practice, longer hose increases friction loss and handling demands, so knowing the maximum helps you plan your attack with the correct expectations for pump pressure and maneuverability.
