    Dimensions related to Planck's constant H

    Thank you! I've asked another question about fcc fraction packing for a pyramidal structure. Can you take a look at it and help me out? I'm really lost on that one.

    Calculate the packing fraction of an FCC pyramid

    Well, it's a pyramidal structure that I'm supposed to figure out as described in the initial segment of the question. Do I treat it as a cube? I'm completely lost here.

    Calculate the packing fraction of an FCC pyramid

    Homework Statement Solids consist of a crystalline lattice of atoms-a unit cell that has a certain configuration of atoms that is repeated over and over. The picture that I can't post here, shows a pyramidal structure of metal spheres. The base is 8 spheres by 8 spheres with a height of 8...

    Dimensions related to Planck's constant H

    Consider a system where the three fundamentally important quantities are the speed of light C with dimensions (L)/(T), Planck's constant H with dimensions (M)(L)^2/(T), and the mass of the proton M sub p with dimension (M). a) What combination of ratios and/or products of C, H, and M sub p will...
