# 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.)?

##### 2 Answers

#### Answer:

#### Explanation:

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

#### Answer:

Approximately

#### Explanation:

Density is defined by the equation

where

We have a cube with sides

So, the volume of this cube is

Now, we just plug in values into the density equation.
