One edge of a copper cube is carefully measured and found to be 2.162 cm. An atom of copper is a sphere 0.2560 nanometers in diameter. Assuming that the volume of the cube contains nothing but copper atoms, how many copper atoms are contained in the cube? (the volume of a cube is the length of one edge raised to the third power. the volume of a sphere is 1.333 x n x the radius of the sphere raised to the third power)
