**Henry**, Monday, February 27, 2012 at 5:13pmVr=0.100 * 0.08 * 0.06=4.8*10^-4 m^3 =

480 cm^3.

Vb=0.04 * 0.08 * 0.06 = 1.92*10^-4 m^3 = 192 cm^3 = Vol. below surface.

Vb = (Dr/Dl)*Vr = 1.92*10^-4 m^3.

(Dr/1354)*4.8*10^-4 = 1.92*10^-4.

Multiply both sides by 1354:

Dr*4.8*10^-4 = 2599.68*10*-4.

Dr = 541.6 kg/m^3=Density of rectangle.
