Question

A certain cube of brass is measured to have a mass of 562 g.

Based on the mass, as well as the density of brass (8.5 g/cm²),
determine the length of one side of this brass cube.
Answer in units of cm

Answer 1

So the density for this is 8.5g/cm3. And the mass is 562g. So the formula for density is mass/volume. In this case, 8.5g/cm3=562g/v
So using the triangular method, volume is equal to mass / density. So 562 / 8.5. This will give us 66.11764705882353. Round this to the nearest 3d.p will be 66.118cm3
