For 80 square feet you will need a 360 4" x 8" bricks.
450 bricks
Approximately 648 bricks will be required. You have to revise that up a little bit for wastage.
The way to calculate the number of bricks is to calculate the area of the walk and then divide by the area of a single brick. One very important point - the same units must be used for both areas (whether you choose inches, feet or anything else, it doesn't matter, you will get the same answer).The area of the walk is 6x24 square feet and, as there are 12 inches in a foot, this equals (6x12)x(24x12) square inches. This equals 20736 square inches.The area of a brick is 4x8 = 32 square inches.Dividing one by the other, the number of bricks required, N, is given by:N =20736/32= 648 bricks exactly.
18' x 16' (288 square feet) = 32 square yards.
