Body weight 4 kg. Determine the pressure on the floor if the support area is 150 dm2.

As we reliably know, in order to calculate the value of pressure, it is possible to use the formula known from the school curriculum:

p = F: S.

Let us determine what value will be equal to the force with which this body presses on the floor, if from the condition of our problem we know for sure that its mass is 4 kilograms:

F = 4 * 10 = 40.

Now we can calculate what the pressure that the specified body exerts on the floor will equal:

150 dm2 is the same as 1.5 m2;

40: 1.5 = 26, (6).

Answer: 26, (6) Pa.
