# A piece of metal weighs #3.94# #g# and has a density of #5.674# #g##/##cm^3#. What's the volume?

##### 1 Answer

#### Answer:

The volume is

#### Explanation:

The formula for density is

**Given**

**Unknown**

**Solution**

Rearrange the equation to isolate

Remember when you divide by a fraction like

The Density Pyramid below can help you remember how to solve density problems. Cover the variable for which you need to solve. The placement of the known variables on the pyramid will indicate how to solve.

For example, if you need density, cover D. M is over V, so you divide Mass by Volume.

If you need volume, cover V. M is over D, so you divide Mass by Density.

If you need mass, cover M. D is next to V, so multiply Density times Volume.
