Density of the rock
= Mass / Volume
= (15 g) / (3 cm³)
= 5 g/cm³
= Mass / Volume
= (15 g) / (3 cm³)
= 5 g/cm³

Density is Mass/Volume
15g/3cm³ = 5 g/mL <<< in the CGS system
If you want this in KMS:
5 g/mL (1kg/1000g)(1000mL/L) = 5 kg/L
15g/3cm³ = 5 g/mL <<< in the CGS system
If you want this in KMS:
5 g/mL (1kg/1000g)(1000mL/L) = 5 kg/L
