To find the density of an object, you have to divide the mass by the volume.D=M/V.

so first you have to find the mass and the volume. to find the volume you multiply the

length, width, and height. Say that you have a box and the mass is 300 grams, and

10 cm long, 5 cm wide, and 3 cm high.  when you multiply those together it equals

150cm3. Now you have to divide the mass by the volume, 300g/150cm3. when you

divide it comes out to 2g/cm3.

you do it to both rectangles or shapes and whichever one has the higher number it

is more dense
