THIS QUESTION HAS ME GOING CRAZY!!

**Steve**, Sunday, September 1, 2013 at 1:08pmdensity is mass/volume.

So, twice the mass, twice the density.

twice the volume, half the density. So, for cylinder 2, we have

(1/1.35) / (1/.792) * 2.70 = 1.584

**DrBob222**, Sunday, September 1, 2013 at 1:17pmd1 = m1/v2 = 2.70 g/cc

m1 = 1.35*m2 so

m2 = m1/1.35

V1 = 0.792*v2 so

v2 = v1/0.792

d2 = m2/v2

d2 = (m1/1.35)/( v1/0.792)

d2 = m1/1.35 x 0.792/v1 but

m1/v1 = 2.70

then d2 = 2.70 x (0.792/1.35) = ?

Check this.
