Math CentralQuandaries & Queries


Question from Donna:

If I want to buy 10 yards of rubber mulch (bulk), but it only comes in 20 pound bags, how many bags do I need to buy?

Hi Donna,

I would carefully check the bag to see if it gives a volume, perhaps in cubic feet, otherwise I would ask where you plan to purchase it.

I did som searching but I am not sure all the products are the same. I found an online calculator at

but it wouldn't work for me.
