Which answer is false? Density is:

A

property of a matter

B

volume/mass

C

mass/volume

D

amount of substance per cubic centimetre

How do you calculate the Volume of a cylinder?

calculate the volume of this cube

$$p=\frac{m}{V}$$

$$p=(\frac{g}{c{m}^3})$$

calculate the density of this cube

$$p=\frac{m}{V}$$

$$p=(\frac{g}{c{m}^3})$$
