The pressure on the top face of the block is 14,000 N/m².

What is pressure?

The pressure experienced by an object is force per unit area of the surface. The pressure experienced  by the object increases with increase in the applied force and decrease in surface area.

The pressure on the top face of the block is calculated as follows;

P = F/A

where;

  • F is applied force
  • A is top face area

P = (3.5 x 10³)/(0.25)

P = 14,000 N/m²

Thus, the pressure on the top face of the block is 14,000 N/m².
