an object has a mass of 615 grams and a volume of 105 cm2 what is the density of the object

## I assume mass (m) of 615 g and volume (V) of 105 (cm)^3. The density then is: m/V=5.857 g/(cm)^3 = 5857 kg/m^3

The formula xxx density xxx

ρ = m/V, where

m is the mass of the object

V is the volume of the object

.

Our object has a mass of:

m = 615 g

and a Volume of:

V = 105 cm^3

That means our object's density is:

ρ = m/V =>

ρ = 615 g/105 cm^3 =>

ρ ≈ 5.857143 g/cm^3

.

In SI the unit for density is kg/m^3.

1 gram = 0.001 kg = 10^(-3) kg

1 cm^3 = (0.01)^3 m^3 = 10^(-6) m^3

.

So, our density of ρ ≈ 5.857143 g/cm^3 is in SI:

ρ ≈ 5.857143 * 10^(-3)/10^(-6) kg/m^3 =>

ρ ≈ 5.857143 * 1/10^(-3) kg/m^3 =>

ρ ≈ 5.857143 * 10^3 kg/m^3 =>

ρ ≈ 5857.143 kg/m^3

.
