Answer 2

Answer:

10,000 N/m²  or  Pa

Explanation:

Surface area of one face of the cube = 10*10 cm² = 0.01 meter²

weight of the cube = 10 kg = mass * gravity = 10kg * 10 metres/sec² = 100 newtons

pressure or stress exerted by the cube on the table = force / area through which the force acts

                 = weight / surface area of cube 

              = 100 newtons / 0.01 meter²  = 10,000 N/m²  or  Pa
