Hi Pam,

I'm not sure whether you meant the cube had a volume of 2cm

^{3}or a side length of 2cm, so I will work out the problem both ways.Volume = 2cm

^{3}So you need to find the density of a cube with volume(V) = 2cm

^{3}and mass(m) = 500g.The units of density are mass/volume, so all you need to do is divide the mass by volume.

Density = 500g/2cm

^{3}= 250g/cm^{3}Side = 2cm

The units of density are mass/volume, so we need to first find the volume of the cube, then divide the mass by the volume.

Volume = length

^{3 }= (2cm)^{3}= 8cm^{3}Density = 500g/8cm

^{3}= 62.5g/cm^{3}
