If the object is small enough to place into a graduated container, note the level of the water and then totally immerse the object (being careful that no air bubbles remain under it) by pushing it just below the surface. Note the difference in the water level, and calculate the volume by multiplying the difference in water level times the area of the graduated container.

Half fill a graduated glass beaker with water and note the level. Place irregularly shaped object into the beaker. Note the new level. The difference between the two levels is the volume of the object. cw: OK, that method works for objects that don't get wet -- like steel. Tissue paper would not be a good candidate. Also, if the object floats, you have to submerge the object.
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.
If possible, fully immerse the object in water, and measure the volume of displaced water.
It is the displacement method.
