Not assembled yet, but I bought the wood to make the first garden box! It’s 10x5x1, so it will be about 50 cubic feet. I’m lucky to be putting a bed where there is currently new sod, so it will be easy to tear up the grass. Now I just need soil!
I found a great online calculator to help determine how much soil is needed for a new raised bed. http://www.gardeners.com/how-to/soil-calculator/7558.html
