Nice explanation sir. Just loved it in kannada....

I have one question Why you give c/a = 1.633

[phantom_steeze]

good one, just left out the 8 as part of the denominator, thus the denominator is supposed to be 8*9√3 *1.633....

[rohanravi]

how to find 'c' is out of screen, how can we understand!!

[Richardstephano-ds]

You devide well but durring simplify you forget that 8 in cube of a and that 2 of in base area where are?

[jasonmarx]
