Find the volume of a brick:
Convert inches to feet
+%28+8%2F12+%29%2A%28+2.75%2F12+%29%2A%28+2%2F12+%29+=+%281%2F12%29%5E3+%2A44+
+V+=+44%2F1728+
+V+=+11%2F432+ ft3
-------------------------
The volume of the wall is:
+22%2A3w+=+66w+
-----------------------
The number of bricks is:
+66w+%2F+%28+11%2F432+%29+=+6%2A432+
+2592w+ bricks
----------------------
