The dimensions of a brick that weighs 25 n are 0.19 m × 0.07 m × 0.095 m. what pressure does the brick exert on the ground if it is resting on its largest face? 1385 n/m2 19,786 n/m2 3759 n/m2 1900 n/m2

1385 N/m^2

Explanation:

The pressure exerted by the brick on the ground is given by:

where F is the weight of the brick and A is the area of its largest face.

The area of the largest face is given by the two largest sides of the brick, therefore:

The force exerted by the brick is the weight:

So, the pressure is
