Now here's a poser.
Take a cube of material with length of each side = 30mm, ie. volume=27mL
Drill a 10mm dia hole from the cenre of one face right through the material. Call that the X axis.
Now drill two similar holes in the Y and Z axes - again in the centre of the faces so all three holes intersect.
Question: What volume of material is left?
