Solution
The correct option is B C
Iron cuboid has the largest mass among all. So, it will exert a good amount of pressure.
Also, the dimensions have to be relatively small in order to handle them well for practical purposes.
Thus, the best choice will be Iron cuboid of dimensions 5cm × 10cm × 50cm
