How much did the pennies weigh in pounds (lbs)?

3520 pounds

Step-by-step explanation:

First, we have to find how many pennies equal 2.2 lbs

By seeing that 1 penny equals 4 grams, we can divide 4 into 1,000

It is 250 pennies per 2.2 lbs

Now, it wants 400,000 pennies

So we can do 400,000/250

Which is 1600

1600*2.2 is 3520

So the answer is 3520 pounds
