we know that mass = volume * density\nin the first case, mass = 278.1g\nvolume of the cube = 3*3*3 = 27 cm^3\ntherefore density = mass/ volume\n density of steel = 278.1/27 = 10.3\nThrefore the mass of 1 cm^3 of steel= volume * density\n                                    = 1 * 10.3\n                                    = 10.3 g\n\nNote: denstiy of any material is always a constant- it is an intrinsic property of the material. It is important to get these concepts right when you study them so that you can have a good foundation for higher studies. Please promise me that once you understand how to do this problem, you will try it on your own. Thanks. goodluck

hmmm ...\n\n(2.5 x 10^3  ) x (.0685) = .17125 x10^3 = 1.7125 x 10^2 g

z/0.23-0.11=0.17\n=>z /0.23=0.17+0.11=0.28\n=>z=0.28X0.23 =0.0644=0.1 (rounded to the nearest tenth)\nTherefore,(D) is correct

P = (you guessed it) F / A.\n\nP = 37 / 0.0084 = 4404.76 Pa\n\n1 Pa = 1 / 133.322 mmHg\n\nP = 4404.76 / 133.322 = 33.0 mmHg.\n\nIs this beginning to make sense now?
