There are MANY different types of gravel - one for each of your needs. If it is for your driveway, the gravel is usually made of crushed rocks (in large sizes). If you're looking for the smaller version of gravel, the sand-like verson, they also vary from sizes down to a grain of sand, to the driveway-like gravel.
It depends on how thick you want the gravel to be. All dimensions will be in feet. (fractions) Width x length x depth divided by 27 equalls cu. yds.

You will need 0.12 cubic yards of gravel for an 8x8x90' area.
You cannot directly convert cubic yards to square yards because they measure different things: volume vs. area. Cubic yards measure volume, while square yards measure area. To find how many square yards cover the same area as a cubic yard of gravel, you would need to know the thickness or depth of the gravel layer.
