Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

how do I determine how many cubic yards of mulch I need to cover 387sq feet?

it depends on how thick a layer of mulch you are laying down.

387 square feet x 1inch thick = 32.25 cubic feet ( 387 divided by 12 )

one cubic yard = 3 ft x 3 ft x 3 ft = 27 cubic feet

32.25 cubic feet divided by 27 cubic feet (cubic yard) = 1.194 cubic yards.

hope that helps.
