Question

Frank has a sample of steel that weighs 80 grams. If the density of his sample of steel is 8 g/cm3, what is the sample’s volume

Answer 1

Answer: The volume of the piece of steel is $10cm^3$

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Given : Mass of steel = 80 grams

Density of steel = $8g/cm^3$

Putting in the values we get:

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

$Volume=10cm^3$

Thus the volume of steel is $10cm^3$

Answer 2

Given:

Mass of the sample = 80 g

Density of the sample = 8g/$cm^3$

To find:

Volume of the sample = ?

Formula to be used:

$Density = \frac{Mass}{Volume}$

Calculation:

$Density = \frac{Mass}{Volume}$

$\frac{Density}{Mass} = Volume$

Substituting the given values in the formula, we get

$Volume = \frac{Density}{Mass}$

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

Volume = $10cm^3$

Conclusion:

The volume of the sample is found to be $10cm^3$.
