Question

A block of metal has a volume of 56,000

cm3 and a mass of 280,000 g.
Find the density of the metal in kg/m3.
kg/m3

Answer 1

To find the density of the metal in kg/m3, we need to convert both the volume and mass to the appropriate units and then use the formula:

Density (in kg/m3) = mass (in kg) / volume (in m3)

We can start by converting the volume from cm3 to m3:

56,000 cm3 = 56,000/1,000,000 m3 = 0.056 m3

Next, we need to convert the mass from grams to kilograms:

280,000 g = 280,000/1000 kg = 280 kg

Now we can use the formula to calculate the density:

Density = 280 kg / 0.056 m3 = 5,000 kg/m3

Therefore, the density of the metal is 5,000 kg/m3.
