The density of a is higher than that of B. the pressure of these two cubes on the horizontal ground is as follows A. P a = P B B. P a > P B C. P a < P B D. All of the above are possible

P = f / S = g / L & # 178; = mg / L & # 178; (L is the edge length of cube)
V=m/ρ
Two cubes have the same mass
Since the density of nail is large, the volume of nail is small, and the edge length of nail is also small
Then p a > P B
Choose B
