Use the Format Data Series pane to apply the first bevel effect to the top of the pie chart with a width and height (in that order) of 512 pt. Then apply the same effect to the bottom of the pie chart with a width and height (in that order) of 512 pt. Change the surface material of the chart to Metal (fourth material under Standard). Do not close the Format Data Series task pane.

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
