Lesson: Calculating Density High School PhysicsPhysics
In this lesson, we will learn how to use the formula ρ = M/V to calculate the densities of different materials and objects.

Two spheres have the same mass, but the second sphere has a volume half as big as the first. How much greater is the density of the second sphere than that of the first sphere?
A scientist has three cubes of different materials. Each cube has a volume of 125 cm3. She weighs each cube to find its mass, and her results are recorded in the table shown. Which material has the highest density?
|Material||Volume (cm3)||Mass (kg)|
A small cube of iron has sides with length 0.15 m. If the mass of the cube is 26.6 kg, what is its density? Give your answer to 3 significant figures.
