the volume is 7.15 volume is length*width*height
the mass is 22.6
mass/volume= density
22.6/7.15= 3.16 (rounded)
lol i forgot it to i had to look it up

Density is mass divided by volume
mass=22.6g
volume=length*width*height=2.5*1.3*2.2=7.15cm cubed
density=mass divided by volume=22.6/7.15=3.16g/cm cubed
to 3 significant figures

volume is length*width*height, and the density is the mass divided the volume.

length x wixth x height = volume
mass(grams)/volume(cm3)
once you have the volume divide the mass by it, and put it in the format above. You need to put it as a rate so make sure the cm3 is one, so you don't have put it.
