2. How can you use a balance scale and a metric ruler to find the density of a rectangular solid?

mass = triple beam balance; volume = l X w X h

Explanation:

Measure the solid to determine its length, width, and height. Multiply all three to get its volume. Weigh the solid to determine its weight. Divide weight by volume to get density. Convert as needed to the appropriate units.
