Question

To observe and compare the pressure exerted by
solid iron cuboid, a student marked all the faces
of cuboid from 1 to 6. After doing the experiment
with all faces of cuboid, he observed that
A. adjacent faces of cuboid exerted the same pressure
B. all the faces of cuboid exerted same pressure on the sand
C. opposite parallel faces of cuboid exerted unequal pressure on the sand
D. opposite parallel faces of the cuboid exerted
some pressure on the sand​

Answer 1

After doing the experiment with all faces of cuboid, he observed that opposite parallel faces of cuboid exerted unequal pressure on the sand. (option C)

• However, it can be deduced from the sentence "opposite parallel faces of cuboid exerted unequal pressure on the sand" that these faces put uneven pressure on the sand.
• This shows that the cuboid did not apply the same pressure to the sand on opposing parallel faces, which may be the result of variations in surface area or weight distribution.
• When the solid iron cuboid is positioned on its smallest surface area, the sand depression is more pronounced.
• In comparison to other surfaces with bigger surface areas, the surface with the smallest surface area exerts more pressure.
• The pupils were able to comprehend the theories of force, area pressure, depression, and their interdependence.

Hence, After doing the experiment with all faces of cuboid, he observed that opposite parallel faces of cuboid exerted unequal pressure on the sand.
