Dear 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 FaceBook page

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

I need to know how much stone I will need to cover an area that is 30 feet long by 20 feet wide. Also the gravel will be 5 inches deep.?

30 x20x .415 / 27 = 9.22 cubic yards

Brake down for inches to 10ths divide 10 by 12 this will convert into 10ths times your inches thickness desired. (Apx.)

1" = .083
.083x5 = .415
lenght x Width x Thichness
20 x 30 x .415
