Based on your given criteria and the general properties of sandbags, the following statements are true:
B. Sandbags cannot be used over and over again, but they cost less than $4,000.
Sandbags are relatively inexpensive and can be an effective temporary solution for flood prevention. However, they are typically not reusable year after year because they degrade over time, especially if exposed to floodwaters.
A. Sandbags can be set up in less than an hour, and they can be reused many times.
C. Sandbags can stop floodwaters while still allowing the doors to open.
These statements are false because:
- Although sandbags can be quickly deployed, setting up enough sandbags to effectively stop floodwaters of 24 inches within an hour might be challenging.
- Sandbags generally do not allow doors to be opened and closed once they are in place, as they would physically block the doorways.
Thus, the correct selection is:
B. Sandbags cannot be used over and over again, but they cost less than $4,000.
Needs for flood barriers:
- Must stop floodwaters that are 24 inches high
- Must allow the doors to open and close
- Must be reusable year after year
- Must cost less than $4,000 total
- Must be set up in 60 minutes or less
Which of the following statements about sandbags are true? Select all that apply.
A. Sandbags can be set up in less than an hour, and they can be reused many times.
B. Sandbags cannot be used over and over again, but they cost less than $4,000.
C. Sandbags can stop floodwaters while still allowing the doors to open.
