In class, we have discussed density as being "how much matter (stuff) something has in a given (specific) volume.

We have also used the formula for calculating density. This formula can be written several ways but they all mean the same thing:

Density is equal to Mass divided by Volume.

or

Density = Mass ÷ Volume

or

d = m / v

Units used in Density.

We measure mass in units like grams (g) and kilograms (kg).

We measure volume in in units like milliliters (ml) and cubic centimeters (cm³). One milliliter (1ml) is equal to one cubic centimeter (1cm³). Written another way, 1 ml = 1 cm³.

We write the unit for density as grams per milliliter (g/ml) or grams per cubic centimeter (g/cm³).

Here's an example of using the above information:

Tanya needs to find the density of a brick.

First, Tanya measures the mass of a brick. She finds that the brick's mass is equal to 32 grams.

Next she wants to know its volume. She measures the brick's length, width and height. She finds that the brick's dimensions are 4 cm x 2 cm x 2 cm. By multiplying the measurements she finds the volume to be 16 cm³.

Tanya then uses the density formula to calculate the brick's density.

d = m / v ----->

d = 32 g/ 16 cm³ -----> 2 g / cm³

The density of Tanya's brick is 2 grams per cubic centimeter (2 g/cm³). We can also write this as 2 grams per milliliter (2 g/ml).

We have also used the formula for calculating density. This formula can be written several ways but they all mean the same thing:
