the relative density of steel is 7.8 side 10cm. what volume of the steel has a mass 8kg
I don't know what "side 10 cm" means.
If density = 7.8 g/cc the
mass = volume x density
8,000g = volume in cc x 7.8 g/cc
Solve for volume.
To find the volume of the steel, we can use the formula:
Mass = Density * Volume
Given that the mass of the steel is 8 kg and the density of steel is 7.8 g/cm³ (note: we need to convert the density to grams per cubic centimeter), we can rearrange the formula to solve for volume:
Volume = Mass / Density
First, let's convert the density from g/cm³ to kg/cm³:
Density = 7.8 g/cm³ = 7.8 * (1 kg / 1000 g) / (1 cm³)
Density = 0.0078 kg/cm³
Now we can substitute the known values into the formula to find the volume:
Volume = 8 kg / 0.0078 kg/cm³
Volume ≈ 1025.64 cm³
Therefore, the volume of the steel with a mass of 8 kg is approximately 1025.64 cm³.
To find the volume of the steel with mass 8kg, we need to use the formula:
Density = Mass / Volume
Rearranging the formula, we have:
Volume = Mass / Density
Given that the mass is 8kg, and the relative density of steel is 7.8, we can substitute these values into the formula to calculate the volume.
Volume = 8kg / 7.8
Dividing 8kg by 7.8 gives us the volume:
Volume = 1.03 m^3
Therefore, the volume of the steel with a mass of 8kg is 1.03 cubic meters.
