How would you measure the density of this Spiderman toy? 
1. Take the mass on a scale.
2. Fill a graduated cylinder with water and measure the initial volume.
3. Drop the toy in so it is fully submerged.
4. Record the final volume.
5. Subtract the final volume from the starting volume to get the volume of the toy.
6. Divide the mass by the volume to get the density.
