Math CentralQuandaries & Queries


Question from Robert, a parent:

We have a section that is 20ft long by 14ft wide and 4inches deep, the bags of sand are
.5 cubic ft. How many bags of sand do we need to fill this space evenly.

Hi Robert,

You can use our volume calculator. I did so and found that you need almost 200 bags of sand. If you are really going to do this I suggest you find a more economical way to purchase the sand.
