##### 1 Answer

Density is a comparison of the mass of an object and the volume of that object.

This equation can be rearranged algebraically to solve foray of the values.

Let us look at two sample problems.

A rectangular prism has a mass of 42.0 grams and has dimensions of 2 cm in width, 6 cm long and 0.5 cm in height. What is the density of this object?

Volume of a rectangular prism is

Now the density is

A rectangular prism has a mass of 42.0 grams and has dimensions of 2 cm in width, 6 cm long and 0.5 cm in height. What is the density of this object?

Volume of a rectangular prism is

Now the density is
