A piece of metal of mass 800g and volume 20cm^3 is suspended
To find the density of the metal, you need to use the formula:
Density = Mass / Volume
1. Start by converting the mass from grams to kilograms. Since 1 kg = 1000 g, divide the mass by 1000:
Mass in kg = 800 g / 1000 = 0.8 kg
2. Now, convert the volume from cm^3 to m^3. Since 1 m^3 = 1000000 cm^3, divide the volume by 1000000:
Volume in m^3 = 20 cm^3 / 1000000 = 0.00002 m^3
3. Use the formula to calculate the density:
Density = Mass / Volume = 0.8 kg / 0.00002 m^3 = 40000 kg/m^3
So, the density of the metal is 40000 kg/m^3.
