Two bricks lie on the ground, one laying the flat on the ground and one standing up. Are both of these bricks exerting the same force upon the ground?
-
Yes, assuming they have the same mass. The normal force has to balance out their weight.
Bonus info: What will be different will be their pressures, which is the force per unit area. That's why a brick hurts more if a corner sits on your foot than if it sits on its side.

Yes but not the same pressure.
Pressure = Force / Area. The area is different for 3 of the bricks orientations and that makes the pressure quite different.
Force on the other hand is F = ma which is independent of orientation.
