a sheet of glass has a density of 2.5 g/cm cubed , convert to kg/m cubed

Question

please help, im so confused

Answer 1

2.5 g converted to kg:  2.5 g x 1 kg/1000 g = 0.0025 kg = 2.5x10^-3 kg

cm³ converted to m³:  1 cm³ x 10^-6 m³/cm³ = 1x10-6 m³

Thus, the conversion of 2.5 g/cm³ to kg/m³ would be 2.5x10^-3 kg/10^-6 m³ = 2.5x10³ kg/m³ = 2500 kg/m³
