If each ream is 32 ounces, and there are 10 reams in the case, then we need to multiply 32x10.
We can simplify the problem though, so let's do that!
30x10=300
2x10=20
300+20=320.
Now, there are 16 ounces in a pound. SO. We need to divide 320 by 16.
320÷16=20
we know because 32÷16=2
so we add a zero onto our answer since we added a zero onto 32.
In conclusion, the answer is 20lbs
