Question

Aluminium has a density of 2700 `( kg)/m^3`. What is the density in `g/(cm^3)`?

Answer 1

`2.700*g*cm^-3`

Explanation:

`rho=2700*kg*m^-3`

`=2700xx10^3*g*(100*cm)^-3`

`=2.700xx10^6*gxx1/(100^3*cm^3)`

`=2.700xx10^6*gxx10^-6*cm^-3`

`=2.700*g*cm^-3`

I always have to double check when I use `"cubic metres"`. A `m^3` (`-=1000*L`) is a HUGE volume.
