5 cu. yd. Bulk Topsoil

96 Feet sq = 13 cu.yards

A cubic yard of material can be spread to cover 100 square feet (10×10 foot area) at 3 inches of depth.

Rachael: You did not mention how big an area nor what it's use. If this is for a standard home lot 5, 000 to 10,000 sq ft) and not a lot of acreage that you don't want to grow anything on, and If you are planning on planting a lawn, shrubs, or trees after you grade then I recommend using only the best top soil as the grading soil will become your top soil so why not have the best ( unless you are filling in spots that are 5 ft deep or deeper) I once installed a train (7 cu ft) of rich organic top soil in a new house where the housing tract ground had been bulldozed and scraped level and had removed much if not all of the top soil. Due to standard requirements of grading for drainage 1/8 to 1/4 inch per foot away from the house and away from neighbors I ended up with a channel that started shallow in back and ended up 3 feet deep in front which required that I construct a different method of drainage. . So in places the top soil was more than a foot deep . As a result of good organic fill dirt (top soil) everything I planted grew in abundance and much better than any neighbors plants who planted the same things I did. Therefore I recommend only using rich top soil for grading lawn and planting areas for shrubs, trees, etc. as every plant wants to have good deep rooots in soil that holds some moisture . There are two tools for speading and compacting a few inches of top soil , Both are approximately 3 ft wide hand rollers. One is a round metal cage full of holes every 1/4 inch apart that you fill with top soil and it drops top soil down on the ground in a 3 ft swarth as you roll. And the other tool is a round empty cask that you fill with water to add weight to compact the top soil by rolling over the deposited soil after you lay down a few layers. These tools allow a much better way of both grading and laying down an even layer of soil to your desired depth. Once the soil is compacted lightly sprinkle water on the new soil and any water puddle you see will tell you where the soil is lower than the surrounding soil and thus tells you where it needs more soil and needs recompacted. ( the water should also run away from the house when grading a home. These rollers are also much easier than using a shovel and rake to spread the soil evenly particularly since it is not as easily nor as evenly compacted . I do not know the name of these tools and none of the professional landscapers I talked to in my area have even heard of them where I now live. But try some specialty shops that sell and rent equipment.
