Question

Gina was given an irregularly shaped piece of metal and was told that the density of the metal was 10 g/cm3. She measured the mass of the piece to be 210 g. What was the volume of the piece of metal Gina was given?

Answer 1

The volume of the piece of the metal Gina is found to be 21
`cm^(3)`

Step-by-step explanation:

Given density of the metal = 10 g/
`cm^(3)`

Given mass of the piece of the metal = 210 g

Assuming volume of piece of metal to be V
`cm^(3)`

The expression for the density is shown below

`\textrm{Density} = \displaystyle \frac{\textrm{Mass of piece of metal}}{\textrm{Volume of piece of metal}}\\10 \textrm{ g/cm}^(3) = \displaystyle \frac{210 \textrm{ g}}{V} \\V = 21 \textrm{cm}^(3)`

Volume of the piece of metal = 21
`cm^(3)`
