Question
Object A has a mass of 200 g and a volume of 40 cm³. Object B has a mass of 240 g and a volume of 60 cm³. Which object is denser?
Show answer
Answer
Object A is denser.
Explanation
Density A
=
\( \dfrac{200\ \text{g}}{40\ \text{cm}^3} = 5\ \text{g/cm}^3 \)
Density B
=
\( \dfrac{240\ \text{g}}{60\ \text{cm}^3} = 4\ \text{g/cm}^3 \)
- Object A has a density of 5 g/cm³.
- Object B has a density of 4 g/cm³.
- Since 5 is greater than 4, A is denser.
Object A (5 g/cm³) is denser than object B (4 g/cm³).
