Same mass different volumes.

Looking at the images on the left, we can see that the kilogram of Cornflakes(TM) is much larger in volume than the kilogram of sugar. The box of cornflakes is about six times larger in size than the bag of sugar. But, both have the same mass!  This is because the space between the flakes is much larger than the space between the sugar granules.

Same volume different masses

a volume of 640 cm³ or 0.0006 m³.

in the same volume of 640 cm³ or 0.0006 m³

• the density of sugar is 1083 kg per m³.
• the density of cornflakes is 200 kg per m³.

So, according to the equation above this tells us that sugar is at lease five times more dense than cornflakes. But, don’t take out word for it, try this experiment at home.
