Question

pieces of cake with each piece having a side length of __________
inches.

Answer 1

5.55% = 1/18

so, cut the cake into 18 equal squares.

The cake is twice as long as it is wide, so that means cut half the cake (6 3/4 x 6 3/4) into 9 pieces, each with a side of 1/3 * 6 3/4 = 2 1/4 inches.
