the density of a copper is 9.86g/cm3
what's the mass of the cube
mass = density × volume
You're are given the density, but still need the volume - was that also stated in the question?
it was 10 3 and 5
To find the mass of the copper cube, we need to know the volume of the cube. However, the information provided in the question doesn't include the volume.
The formula to calculate the mass of an object is:
Mass = Density x Volume
Since we don't have the volume of the copper cube, we cannot directly calculate the mass.
If you have the dimensions of the cube (length, width, and height), you can calculate its volume using the formula:
Volume = Length x Width x Height
Once you have the volume, you can multiply it by the density of copper (9.86 g/cm^3) to find the mass.
