you would need 12...
A 12 x 12 inch brick is 1 square foot. A 20 x 20 (foot) patio is 400 square feet, so you would need 400 bricks.. this assumes you are butting the bricks fairly tight, not leaving large seperations between them, etc...
1 yard of 1" crushed stone
about 5kg with a stand
225 bricks. 16in * 16in = 256 sq. in. 20ft = 240in. 240in * 240 in = 57,600 sq. in. 57,600 sq. in. / 256 sq. in. = 225. 225 bricks is your answer.
You need 100 12 by 12 inch stones to cover a 10 x 10 foot patio. Since the area of the patio is 10' by 10' = 100 square feet, and each stone is 1 foot * 1 foot = 1 square foot, 100 square feet divided by 1 square foot = 100.
It works out to about 13.1 bags for every inch deepyou're planning on.
It depends on your climate and what the patio cover is made of.

If that is 60" tiles it would take 16 total.
