Question

a METAL cube has a edge length of 11.4 mm and retriceof 667g. Calulate the density of metal...Please help I believe the answer is 148.cm^3....

Answer 1

the Volume of cube is
\[V=s^3\]

density is
\[\rho=\frac mV\]

Answer 2

yes but I need help find volume...ive gotten 1481544mm^3 but needs to convert to cm^3

Answer 3

1481.544

Answer 4

to convert millimeters to centimeters
\[1[\text{cm}]=10[\text{mm}]\]
so
\[1[\text{cm}]^3=(10[\text{mm}])^3=1000[\text{mm}]^3\]

Answer 5

yes but I understand it I keep getten the answer wrong..can you please show me the procedure?

Answer 6

the answer is 4.51g/cm^3 right??

Answer 7

\[\rho=\frac m{s^3}=\frac{667[\text g]}{{(11.4[\text{mm}])^3}}\]\[=\frac{667[\text g]}{1481.544[\text{mm}]^3}\]\[=\frac{667[\text g]}{1.481544[\text{cm}]^3}\]\[\approx 0.4502\tfrac{[\text g]}{[\text{cm}]^3}\]

Answer 8

thanks
