You offered little about what you wanted to measure. So far, you have basic answers. If you have a material that is porous, but you still want to know the density of the material (not the material and the pores). You will need to do a test that eliminates the pores. An oil penetration test will do this. It involves some extras work, but you will get the desired result.
If you are looking for a straight forward Density on a non porous substance, then do the following.
Weight the sample in air and record it
Weight the sample under water and record it
subtract the weight in water from the weight in air and that number is the volume (If the volume is in liters, the weight is in Kg; if the volume is in cc than the weight is in grams, and vice versca). Look up Archemedes principle (sp)

Find the mass of the body using a balance. Then find its volume by calculation if it is a regular body, or if it is liquid use a measuring cylinder, or if it is an irregular body find its voume using the displacement method and a eureka can and measuring cylinder. Density = Mass divided by volume.

You can divide the mass of a sample by its volume. Of course, on the surface of the earth you can also divide the weight of the sample by its volume. For example, water weighs 62.4 pounds per cubic foot. On the moon it would have the same mass but a different weight. Density of a sample can also be determined by comparing it with the density of a known substance. For example, oil with a specific gravity of 0.8 is only 80% as dense as water (and floats!). Multiply 62.4 pounds per cubic foot by 0.8 = 49.92 pounds per cubic foot.

density is the mass per unit of volume of an object,
so to find it, take the mass and divide it by the volume

D=M/V (density equals mass over volume)

Squeeze the item, if it smooshes up easily it is much less dense than an item you can't squeeze and smoosh into a smaller size.
