Jason bought two identical boxes of nails. One box weighs 168 ounces. What is the total weight of the nails Jason bought?

The key here is understanding the question prompt. We are told that Jason bought two identical boxes of nails. The keyword here is 'identical'. Identical means the same. So if one box weighs 168 ounces, the second box must weigh 168 ounces as well.

To find the weight of the two boxes together, you can either add or multiply as shown below.

`168+168=336` ounces, or

`168*2=336` ounces.

You can see either method yields the same result, as...

You can see either method yields the same result, as we would expect.

Now, we might want to calculate how many pounds of nails Jason bought. To do this we must use a conversion factor. There are 16 ounces in 1 pound. 

`336/16=21` pounds.

So Jason bought 21 pounds of nails, in total. Likewise, we can see that each box individually holds 10.5 pounds of nails.
