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.

Concrete Sidewalk

Fri Jul 29, 2005 5:16 am

Hi,
I will be pouring a concrete sidewalk/patio slab and need to know how much concrete I need.
I did my own calculations, but do not trust them.
Here is what I am building (Broken down into measurable squares)
All are measured in inches and will be a 4" slab/sidewalk
1: 36" x 96"
2: 91" x 89"
3: 43" x 44"
4: 90" x 45"

I would like to know how much this converts into for a 4 inch slab/sidewalk and how much it converts into Cubic Feet.
Like I said, I did my own calculations but do not trust them before purchasing the concrete.
Thank you,
Concrete Dummy

where ever you decide to get the concrete from will tell you how many yards you will need ,with those measurements

I multiplied those dimensions by 4" then divided by 1728 cu in/cu ft. I get:
1: 8.0 cu ft
2: 18.75 cu ft
3: 4.38 cu ft
4: 9.38 cu ft

Total: 40.5 cu ft = 1.5 cu yd
