Michael made a cake, in the shape of a perfect cube, for 64
guests at a recent party. The inside of the cake was sponge, and
he iced the cake with red icing. He of course did not ice the
bottom of the cake.
Michael cut each side of the cake into four equal pieces,
making a total of 64 pieces of cake. Each exactly the same size.
How many of the pieces of cake had at least two of their sides
with icing?
