a sheet of aluminum foil that is 11 in wide and 11 in long weighs 8.9gif aluminum has a density of 2.70g/cm3, what is the thickness, in mm, of the foil? (assume that the foil is pure aluminum)
regardless of what people say, cats have a very good memoryi have one who is afraid of balloons, i found out after realizing this that someone had been popping them next to his head constantly while he was a kittenso now he reacts negatively when ever he sees oneconsidering the condition of this shelter (which i hope was shut down.) he may have been abused in some way that involved tin foilalthough we consider it harmless, the cat remembers something that happened where foil was involved.my cat still remembers being hit, and being tossed out the window when he was a kittenhe still cowers when someone tries to pet himi am the only person that he will let touch himall you can do at this point is love him, when you take the foil out, go ahead and let him runthen go and check on him, pet him, and tel him ist ok good luck.
You need to determine volume of the aluminumFirst change 11 inches x 11 inches to metric27.94cm x 27.94cmIf you have 8.9g of foil and foil is 2.7 g/cm3, then you have 3.3cm3 of foil(8.9cm3/2.7cm3)The volume of the foil (3.3cm3) will be equal to the length (27.94cm) x width (27.94cm) x thicknessThat is simplified to 780.64cm2 x thickness equals 3.3cm3Divide each side by 780.64cm2 and you get thickness equals 3.3cm3/780.64cm2Thickness then equals .00423 cm.
