Answer:

A cube of wood is 3 cm on each side. It has a mass of 27 g. What is its density?The volume of a cube is given by s^3. So the volume of this block is 3cm x 3cm x3 cm = 27 cm^3. density = mass/volume =27 g / 27 cm^3 = 1 g/cm^3. the answer is 1 g/cm^3.

What is the mass of a billiard ball that has a volume of 100 cm³ and a density of 2.5 g/cm³?what is the density of a billiard ball that has a volume of 100cm cubed and a mass of 250g? Density = 250g / 100cm^3 = 2.5 g/cm^3.
