pressure = force / area

density = Mass / volume

1atm = 101300 Pa

**bobpursley**, Sunday, November 25, 2007 at 4:14pmpressure= total weight/area

I will be happy to critique your thinking.

**AL**, Sunday, November 25, 2007 at 4:16pmwell what i did was i found the area of the face to be .203 * .0890..then i divided 15/ Area to get pressure then i did 101300 / pressure to get number of bricks..this doesnt work

**bobpursley**, Sunday, November 25, 2007 at 4:28pmsmallest number of bricks will mean the greatest pressure, or smallest area. The side of the brick giving the smallest area will be .0890 x .0570, wouldn't it? The weight on that face gives the greatest pressure.
