Bricks come in many different sizes. One of the most common is 215mm x 65mm. Add space for mortar and each brick will take up an area of about 225 x 75 (about 9 inches by 3 inches).
Therefore there will be 36 bricks in each row and 30 rows so the wall will need a little more than 1000 bricks.

You need to know the measurement of an area when purchasing wall-to-wall carpet or to know how many bricks to buy to pave your patio.
Brick retaining walls are usually 2 walls with a brick row on top. Since you did not include the size of your brick take the size of your wall 25 x 3 = 75 x 2 (the back wall) = 150 sq feel x (how many of your brick per sq foot) + 100 bricks for top row = total brick x 10% waste factor 3.54 bricks per foot would be - 150 x 3.54 = 531 + 100 = 631 + 63 = 694 Note - you may have to fill the void with mortar or concrete if this is to be a "retaining wall" holding back fill dirt or the wall will crack. You also will have to backfill with gravel and provide drainage thru the wall. Study up, you don't want to do this twice.
