These measurements would give you cubic feet. If you are trying to fill that space you would need 1 yard of material which would be three of the MSU bags.
It’s listed at 9 cubic feet = 1/3rd of a cubic yard
This material is a 3/4 crushed gravel and sold as a building aggregate. If you are looking for something uniform in size or with more of a decorative appearance I would suggest ordering a specific gravel for your project
Delivery is not free. Home Depot charges $79 in my area for a truck Delivery from a regional provider. If you are ordering a lot of gravel it is worth it.
It’s been $25/bag fork lift loaded into my trailer. Online I’ve seen mention of a $15 bag deposit, but I’ve never been charged for a deposit on the 8 bags I’ve bought 2019 thru 2021
If you were looking for a 4” layer of gravel each bag would be good for 27 sq.ft., as there are 9 cu.ft. per bag. A 3” layer would be 36 sq.ft. And a 2” layer would be 54 sq.ft. Therefore, as an example, 1100 sq.ft. at 3” would require 31 bags, or 10 cu.yds ($750) When I recently extended a parking area at my house I started with 2” of gravel with fines as the sandy fines that are mixed in with the rock compact really well, then I added this gravel from HD that comes without fines as it looks better.
