A cubically shaped porous composite material (epoxy and carbon fiber) has dimensions of d, e, f and a mass of Wc. After placing the compound in a mixture of sulfuric acid and hydrogen peroxide, the remaining fibers have a mass of Wf. From independent tests, the fiber and resin densities are df and dm, respectively. Determine the volume fraction of the pores in terms of d, e, f, Wc, Wf, df, and dm.
