A cube measures 2.0 cm on each edge and has a mass of 64.7 g. Calculate the density of the material that composes the cube. (The volume of a cube is equal to the edge length cubed.)?
Density is equal to mass divided by volume. You are given a mass of
Because all of the sides of a cube are the same length, the volume just ends up being
Now plug both of those numbers into your density equation
Density is defined by the equation
We have a cube with sides
So, the volume of this cube is
Now, we just plug in values into the density equation.
