A cube with edge length a and density ρ is stationary on a horizontal table. Its pressure on the table is () A cube with edge length a and density ρ is stationary on a horizontal table. Its pressure on the table is () if the edge length of the cube is doubled (the density remains unchanged), then its pressure on the ground is ()
