Each brick is 4/12 * 8/12 = 1/3 * 2/3 = 2/9 sq feet.
To cover 196 sq ft you will require a minimum of 196 / (2/9) = 196*9/2 = 882 bricks.
That is the mathematical answer. It assumes that the shape of the patio, and its dimensions, are such that there is no wastage - that all offcuts are used. In "real" life, you would be advised to get at least 5% extra.
To determine the number of bricks needed for a 5x5 patio, first calculate the area of the patio: 5 feet x 5 feet = 25 square feet. Next, calculate the area of one brick: 3.8 inches x 7.7 inches = 29.26 square inches. Convert the patio area to square inches (25 sq ft x 144 sq in/sq ft = 3600 sq in) and then divide the patio area by the brick area: 3600 sq in / 29.26 sq in ≈ 123 bricks. Thus, you would need approximately 123 bricks for the patio.

A lot !!
About 14 bricks should do it.
To determine the number of bricks needed for an 8x8 patio, you'll first need to calculate the area, which is 64 square feet (8 feet x 8 feet). If you know the size of the bricks you plan to use, you can calculate the total number of bricks by dividing the patio area by the area of one brick. For example, if you use standard bricks that are 0.5 square feet each, you would need 128 bricks (64 sq ft ÷ 0.5 sq ft/brick = 128 bricks).
450 bricks
488 bricks.

1,350 of them.
The question, as stated cannot be answered. You need to know two dimensions of the bricks to find the area of each brick, convert that area into square feet (if necessary) and then divide 256 by the area of each brick. Bricks are not usually square so it would not be appropriate for me to assume that the bricks are 16" by 16".
Gee, a square foot is 12x12, difficult problem.
The first step is to convert the total patio area to inches so we are working with the same units. 100sq ft = 14,400 sq inches. Now we need to calculate the number of square inches each brick takes up. Answer: 36 sq in. Now we just divide the total square inches of the patio by the square inches taken up by each brick: 14,400/36 = 400 bricks. It will take 400 bricks to make a 100 square foot patio.
