# A block of wood 3.0 cm on each side has a mass of 27 g. what is the density of this block

i need help with these density problems i have no idea how to do them..
i tried this one but dont know if its right..
Q:A block of wood 3.0 cm on each side has a mass of 27 g. what is the density of this block?
D=m/v
so.. 3^3=27 which would be the volume?
then i divided the mass(27g) by the volume (27) and got 1g/cm^3...
is this right?

Yes, that is correct. It's that easy

Sometimes we all have trouble accepting that. :)

Wow, rereading how I wrote that, I sound kinda mean! I didn't mean to come off that way! =)

### V= L×W×H=3cm×3cm×3cm=27cm3

V= L×W×H=3cm×3cm×3cm=27cm3
m=27g
d=m/v = 27g/27cm3=1g/cm3

Hope it is easy.
