Answer:

1) 8.4 g/cm³

2) 8400 kg/m³

Explanation:

The formula for getting density is given by :

Density = mass / volume

We need to calculate the density in g/cm³ and in kg/m³.

1) g/cm³

Applying the formula we have :

Density = 252/30 = 8.4

8.4 g/cm³

2) in kilograms per meters cube

We convert the mass to kilograms.

Mass = 252/1000 = 0.252 Kgs

We convert the volume to cubic meters.

1 m³ = 1000000 cm³

30/1000000 × 1 = 0.00003 m³

Density = mass/volume

Substituting we have :

0.252/0.00003 = 8400 kg/m³

II] SI Unit
