I have a solid cube with its dimensions 2 units in length. I have drill-bit of radius 1 unit.
I drill a hole through the centre of each face through to the other side.
When I have finished I am left with 8 identicle corner shapes.
I would like to see the all working for the calculation of the volume of one of these corner bits?
The actual volume was provided in part 1 of the question, see :
I would now like to see how the formula was arrived at.
