First off forgive me if this is a stupid question, I've never been great with math. I'm thinking about buying 6 cubic yards of bulk compost for my garden and in my head that would be just 18 feet squared which seems like a ginormous amount. However, whenever I see someone on the internet post a picture/video of a similar amount of soil it doesn't really look like that much. How does that work?
