Asked by T

A piece of copper 12 cm long, 8.5 cm wide, and .50 cm thick has a mass of 457 grams. What is its density?

D = m/v
D = 457 g / 12x8.5x.50
D = 457 / 51 = 8.96 g/cm^3

Is this correct?

That looks right to me.

by the way iron is also about 8 times as dense as water (1 g/cc or 1000 kg/m^3) and aluminium is less and concrete is about half. That gives you a bit of a check.
