This is a lateral thinking riddle. A hole is empty space by definition, so there is zero soil in it regardless of its dimensions.

This is a wordplay riddle involving Roman numerals and letters. If you take the word 'FIVE' and remove the first two letters 'F' and 'I', you get 'VE'.

But if you remove 'FI' from FIVE, you get VE. Hmm, the riddle must be that half (first half) of F-I-V-E is IV, which is 4 in Roman numerals.
