True

Density = mass/volume

Suppose that a block has a mass of 20 g and a volume of 20 cm^3.

Density = 20 g/20 cm^3 = 1 g/cm^3

Now, you cut the block in half. The half-block has a mass of 10 g and a volume of 10 cm^3.

The density of the half-block is

Density = 10 g/10 cm^3 = 1 g/cm^3

The density stays the same, even though the size of the sample has changed.
