16 x 16 = 256 Sq Ins /144 = 1.78 sq ft per brick
121 / 1.78 = 68 Bricks but I would buy 3 or 4 extra depending on cuts you need to make.
About 14 bricks should do it.

Gee, a square foot is 12x12, difficult problem.
Each brick has an area of 1ft x 1ft ie 1 sq foot. So you would need 308 bricks.
A lot !!

488 bricks.

The answer will depend on the shape of the patio. If it curved then some bricks will need trimming and that will result in wastage and so a larger number of bricks will be required. Also, if the patio leaves a small fractional amount after a whole number of bricks, you will need a lot more bricks. As an extreme example, if the patio is 8 cm*625 metres then you will need 3125 bricks. However, if the shape is convenient, you will require 2500 bricks.

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...
