An introduction to 

density

Goals

• To understand density
• Calculating density
• How to measure volume

The formula for calculating the volume of a rectangular object is:

1. V = l x w x m
2. V = w x h x s
3. V = l x w x d
4. V = l x w x h

Here you see the immersion method, where the volume of a stone is determined.
What is the Volume of this stone?

1. 24cm​3​​
2. 15cm​3​​
3. 9cm​3​​
4. 39cm​3​​

(m³)

(kg)

Volume = 1000 cm³

Mass = 10 kg

Density =?

Volume = 1000 cm³

Mass = 1kg

Density = ?

The stone beside has a mass of 18 grams.
Calculate the density of this stone.

1. 0,5 g/cm^3
2. 2 g/cm^3
3. 9 g/cm^3
4. 18 g/cm^3

A block is 5 cm long, 5 cm wide, 4 cm high and weighs 270 grams.
