Best ResponseYou've already chosen the best response.0First you find the volume which is length x width x height so therefore, 3.2cm x 17.1cm x 4.2cm gives? you do the math.

Best ResponseYou've already chosen the best response.0ok good the formula for density is \[P =\frac{ m }{ v }\] where p is the density, m is the mass and v is the volume so you should apply your values and thats it!

Best ResponseYou've already chosen the best response.0yes It is wise to convert the kg to g so when you get your answer the SI unit will be g/cm^3

Best ResponseYou've already chosen the best response.0Also some people convert the cm to m to obtain \[kgm ^{3}\]. Either way is fine!
