Density - GCSE Maths Definition
Reviewed by: Dan Finlay
Published
Density in maths is a measure of how much mass is packed into a certain volume. It's like asking how many marbles you can fit into a box. If you have two boxes that are the same size but one is heavier because it has more marbles, then the heavier one has a higher density.
To work out density, you divide the mass of an object (which corresponds to how much it weighs) by its volume (the amount of space it takes up). So the formula is
Density = Mass ÷ Volume
Understanding density helps us compare different materials to see which ones are heavier or lighter for the same amount of space.
