The cube has a mass of 3300 g. What is its density? g/cm3 What substance is it? 30cm=length 10cm=width 50cm=height

mathslover (mathslover):

do you know the formula for calculating density? @hungergamer101

OpenStudy (unklerhaukus):

that's no cube

mathslover (mathslover):

@hungergamer101 must have meant to say any cube like structure?

OpenStudy (anonymous):

well the question says cube so thats just what i put. i know the density is 0.22 g, but what i dont know is the substance can someone please help me on that?

OpenStudy (unklerhaukus):

well you have the right number , that is good

OpenStudy (unklerhaukus):

but the unit of density is g/cm^3 so you have 0.22 g/cm^3

OpenStudy (unklerhaukus):

33/150=0.22

OpenStudy (anonymous):

yes... but would the substance be A) Sugar B) Iron or C) Cork

OpenStudy (unklerhaukus):

that makes it easier,

OpenStudy (anonymous):

density less than 1, floats in water density greater than 1, sinks in water
