need to know for textiles assignment :(help?XOXO
I'm not going to give you the answer, but i will help you work them outThe general theme here, is to find the volume of the object, and then divide the mass of the object by the volumeA.) You need the volume of a cube, with sides 4cm long, which is easy for you to work out, then divide the mass given (176g) by this volume and you'll end up with the density of Aluminium in g/cm^3B.) A little more complicated but not muchStart again by finding the volume of the bar, as its a cuboid, this is simple, just multiply all the three lengths togetherThen as before we need to divide the mass by this volume, however the trick here is that the mass they've given you is in kg, so you need to convert to g by multiplying the mass by 1000C.) This is a simple comparison between the two number you calculated, however intuitively you should know which is heavier!
