Too much mulch?

There's a huge area covered with mulch around our house. On any irregular terrain, surface is hard to measure and while I came up with something around 2,200 to 2,800 square feet, this is neither precise nor guaranteed.

That's how, based on my calculations, I just had 8 cubic yards delivered to my home. Yes, that's about 216 cubic feet and if it were spread one inch thick, it'd cover just shy of 2,600 square feet, but will it?

For the moment, I'll have to shovel into that big pile of mulch, carry it on my wheelbarrow to where it's needed, while my dear spouse will spread it as harmoniously and consistantly as she can.

Will there be enough of it? We'll see, but what's certain is that with all the hard work at hand, we won't have to go to the health club for a while!
