Transcript of Density

Density
Starter
What weighs more, a tonne of bricks or a tonne of feathers?
Density - Another compound measure.
Density, like speed, is calculated from simpler measures rather than measured itself.


Like speed, the unit of density tells you how it was calculated.


If one unit of density is kg/cm , can you say how it was calculated?
Calculating with density
A block of metal of volume 9.6 m weighs 5808 kg. Calculate the density of the metal. Give the units of your answer.





A light cloth is made of material with density of 3.7 g/cm . The mass of the cloth is 592 grams. Calculate the volume of material used to make the cloth. Give the units of your answer.
L.O. - Calculate with density

A block of metal of volume 9.6 m weighs 5808 kg. Calculate the density of the metal. Give the units of your answer.

5808 = 605 kg/m

A light cloth is made of material with density of 3.7 g/cm . The mass of the cloth is 592 grams. Calculate the volume of material used to make the cloth. Give the units of your answer.

3.7 g/cm = 592 g ? = 592 ? = 160 cm

A block of metal of has a mass of 58.08kg. The block is in the shape of a cuboid that 4 metres long by 2 metres wide by 1.2 metres high. Calculate the density of the metal.



Volume of metal = 4 x 2 x 1.2 = 9.6 m

Density = 58.08/9.6 = 6.05 kg/m
