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.
