How do I find the density: a wooden cube has an edge length of 6 cm and a mass of 137.8 g. Round to the nearest thousandth

Answer 1

Hi Christina! The formula for density is: density = mass / volume. You already know the mass of the cube, so now you just need to find the volume; since you know the edge length, you can use the formula for finding the volume of a rectangular prism (length x width x height) to find the volume of the cube and complete the calculation.

Answer 2

Density = Mass/Volume

The volume of a cube is the length of an edge cubed = 6**3 = 216 cm**3

Mass is given as 137.8 g.

Density = 137.8 g/216 cm**3 = 0.638 g/cm**3
