Chem question? 2. a block of material has a volume of 2 m3. it has a mass of 1 × 104 kg. calculate the density of the material sample and express your results in g/cm3 with appropriate scientific notation.

The density (d) is the quotient when mass (m) is divided by the volume (v). It is specified that the densities be in units of g/cm³. So, there is a need to convert first the given mass and volume to proper units. The calculations are shown below,
                      2 m³ x (100 cm / 1 m)³ = 2.0x10^6 cm³
                     1x10^4 kg x (1000 g/ 1 kg) = 1.0x10^7 g

Calculating for density,
                d = m/v = (1.0x10^7 g) / (2.0x10^6 cm³) = 5 g/cm³

The answer is 10 bud

2160ft^3 i think you could use a formala to you out with this in the future
