Two rods of the same weight and equal length have different thicknesses. They are held vertically on the surface of sand as shown in the figure. Which one of them will sink more? Why?

Academic Physics NCERT Class 8

We know that pressure is inversely proportional to the area. Here, rod B is thinner. So, rod B will exert more pressure than rod A. So, rod B will sink more in the sand as it has less cross-section area.
