cement/concrete help

Hi, I am trying to fill in a triangle area with concrete. 8' x 11' x 14' x 3". I was looking at the Sakrete Concrete 80lb bags. I am unfamiliar with this concrete and wanted to know if it needs to be mixed with anything (sand, gavel, cememnt) and how to figure out how many bags I will need to do it.

Thanks for the help.

Area of a triangle is 1/2 x base x height.  You have about 64 square.  That's 36 80# bags for a slab thickness of 4"

 

Frankly, that's a lot of concrete to mix by hand.  With the pre-mix bags, you just need to add water.
