# A "94 g" sample of iron has a length of "2 cm", width of "3 cm", and a height of "2 cm". What is its density?

Sep 14, 2016

The density of the sample of iron is ${\text{7.8 g/cm}}^{3}$.

#### Explanation:

$\text{density"="mass"/"volume}$

The mass is given as $\text{94 g}$.

The volume can be calculated by multiplying the length, width, and height.

$V = 2 {\text{cm"xx3"cm"xx2"cm"="12 cm}}^{3}$

Plug the known values into the density formula.

${\text{density"="94 g"/"12 cm"^3="7.8 g/cm}}^{3}$
