Question

Frank has a sample of steel that weighs 80 grams. If the density of his sample of steel is 8 g/cm^3 what is the samples volume

Answer 1

$d=\frac{m}{V} \ \ \ \Rightarrow \ \ \ \ V=\frac{m}{d}\\\\ d=8\frac{g}{cm^{3}}\\ m=80g\\\\ V=\frac{80g}{8\frac{g}{cm^{3}}}=10cm^{3}$

Answer 2

density is the mass of an object/ liquid per unit volume

formula for density is as follows

density = mass / volume

the mass of steel is 80 g

and density is 8 g/cm³

substituting the values in the equation we can find the volume

$8 g/cm^{3} = \frac{80 g}{volume}$

volume = 80 g/cm³ / 8 g

volume = 10 cm³

volume of the sample is 10 cm³
