1. The problem statement, all variables and given/known data A sheeet of metal is 19.3mm wide and 48.2.mm long. if it weighs 8.171g and the density of the metal is 6.69g/cm63, what is the thickness in mm? 2. Relevant equations V= L*W*H H=V/L*W D=M/V V=M/D 3. The attempt at a solution 8.161g(4sig)/6.69g/cm^3(density, so sig digs not counted, right?) = 1.22137cm^3(4sig) : convert into mm: 1221.37mm(4sig) Area given: 19.3*48.2=930.26 1221.375(4sig) / 930.26(3sig) = 1.31(sig) (thickness) Value comes out properly if multiply all 3 volumes. Did I do the sig-digs correctly? Thanks.
