105 N
Explanation
1. The issue here requires us to use the formula of pressure
, where
is the pressure,
is the force, and
is the area, and solve it to get the force
. In this case, we have pressure
, and the area of the face of the box that contacts with the table
.2. After rearranging the formula, we got
.3. Then substituting the values into the formula, we have
.4. With the calculation, the force exerted by the box on the table will be
.Therefore, the box exerts a force of 105 N on the table.
