we know the legnth is 1 m , it has a diameter of 2m
the specific gravity of the copper is 8.96
what is the mass of the copper ?

Looks like you have a copper rod.
Volume = pi*r^2*l = 3.14*(100cm)^2*100cm = 3.14*10^6 cm^3
g = volume * density = 2.813*10^7 g = 28130 kg ≈ 62,000 lb
That's a big rod of copper! (makes sense it's 6 ft across and 3 feet high)

I assume you're talking about a short cylinder of copper. Use the equation for volume of a cylinder to calculate the volume. Convert the volume into cubic centimeters, and then multiply the volume by the density.

density=mass over volume. Try working it out from there
