To determine which fact is not needed to solve the problem, let's analyze the problem step by step.
The primary question asks: "How much do the barrels in the crate weigh in all?"
To solve this problem, we need to know:
1. How many barrels are in the crate.
2. The weight of each barrel.
Given the information:
- The crate contains 4 barrels of red herring.
- Each barrel weighs 320 pounds.
The number of barrels (4) and the weight of each barrel (320 pounds) are necessary pieces of information to find the total weight of the barrels.
Now, let's look at the third fact:
- A barrel holds about 1000 herring.
This fact tells us the capacity of each barrel in terms of the number of herrings it can hold. However, since the question is only asking for the total weight of the barrels and not anything related to the content or number of herrings, this information is not needed for our calculation.
To sum up:
- We need to know the number of barrels (4) and the weight of each barrel (320 pounds) to solve the problem.
- The information about how many herrings each barrel holds is extraneous for solving the posed question.
Therefore, the fact that is not needed to solve the problem is:
OD. A barrel holds about 1000 herring.
