I'm assuming that you meant to write 3cm3 for the volume.

Density = mass/volume = 21g/3cm3 = 7g/cm3.

Q: What if a cube has the mass of 21grams and volume of 3cm?

3cm, 3cm and 3cm respectively

Volume = (length) x (width) x (height)A cube has all 3 dimensions equal.Volume = (3cm) x (3cm) x (3cm) = 27 cm3

Its volume is 27cm3

12x7x3=252

You cube the length of the side: 3*3*3 = 27 cubic cm.
