A solid block has a mass of 240 grams and a volume of 60 millilitres. What is its density?

1. Density is worked out as mass divided by volume. 2. The mass here is 240 grams and the volume is 60 millilitres. 3. Dividing gives 240 divided by 60, which equals 4. 4. So the density is 4 grams per millilitre. 5. Answering 3 would come from dividing 240 by 80, which is not the volume given. 6. Answering 6 would come from dividing 240 by 40, again not the volume given. 7. Answering 8 would come from doubling the correct result by mistake. _Source: Siyavula Natural Sciences Grade 8 (CC BY 4.0), Density tells us how 'tightly packed' a material is_
