To determine the best choice from a practical point of view for observing and comparing the pressure exerted by three different faces of a cuboid on sand, we need to consider the dimensions of the cuboids and the surface area of the faces that will come in contact with the sand.
Let's analyze each option:
A) Wooden cuboid of dimension 20 cm x 30 cm x 50 cm:
- The surface area of the face that will be in contact with the sand can be calculated as 20 cm x 30 cm = 600 cm².
- The pressure exerted by this face on the sand can be calculated by dividing the weight of the cuboid by the surface area.
- However, since we are not provided with the weight of the wooden cuboid, we cannot accurately determine the pressure exerted. Therefore, this option is not the best choice.
B) Aluminium cuboid of dimension 3 cm x 6 cm x 12 cm:
- The surface area of the face that will be in contact with the sand can be calculated as 3 cm x 6 cm = 18 cm².
- The pressure exerted by this face on the sand can be calculated by dividing the weight of the cuboid by the surface area.
- Again, we are not provided with the weight of the aluminium cuboid, making it difficult to determine the pressure accurately. Hence, this option is also not the best choice.
C) Iron cuboid of dimension 5 cm x 10 cm x 15 cm:
- The surface area of the face that will be in contact with the sand can be calculated as 5 cm x 10 cm = 50 cm².
- The pressure exerted by this face on the sand can be calculated by dividing the weight of the cuboid by the surface area.
- Since the dimensions are smaller compared to the other options, the weight of this cuboid will likely be less, resulting in lower pressure exerted on the sand. Therefore, this option is not the best choice.
D) Iron cuboid of dimension 20 cm x 30 cm x 15 cm:
- The surface area of the face that will be in contact with the sand can be calculated as 20 cm x 30 cm = 600 cm².
- The pressure exerted by this face on the sand can be calculated by dividing the weight of the cuboid by the surface area.
- Since the dimensions are larger compared to the other options, the weight of this cuboid will likely be greater, resulting in higher pressure exerted on the sand. Therefore, this option is the best choice from a practical point of view.
In conclusion, option D) Iron cuboid of dimension 20 cm x 30 cm x 15 cm is the best choice as it has larger dimensions, potentially leading to greater weight and higher pressure exerted on the sand.

It will give us a correct measure of high and low pressure on different faces like 20×30 cm will give lowest pressure and 20×15 will give highest pressure and iron has quite large weight so it will be easy for us to determine pressure and collect information.
