Problem: Which block in the following drawing of a balance is more dense, red or green?

We’re being asked to determine which is more dense between the red and green block.

Density represents the mass of an object or compound within a given volume. It is given by:

$\boxed{\mathbf{Density}\mathbf{ }\mathbf{\left(}\mathbf{d}\mathbf{\right)}\mathbf{ }\mathbf{=}\mathbf{ }\frac{\mathbf{mass}}{\mathbf{volume}}}$

The greater the mass of the object the more dense it is. The greater the volume of the object the less dense it is.
