Henry Ernest Dudeney/Modern Puzzles/143 - The Stone Pedestal

by : $143$

 * The Stone Pedestal
 * In laying the base and cubic pedestal for a certain public memorial,
 * the stonemason used cubic blocks of stone all measuring one foot on each side.
 * There was exactly the same number of these blocks (all uncut) in the pedestal as in the square base on the centre of which it stood.
 * Look at the sketch and try to determine the total number of blocks actually used.
